Fig. 1 has illustrated the operation on nasal sinus before planting tooth.Fig. 1 (A) is the profile of upper jaw nasal sinuses 4 before an operation on nasal sinus, is covered by nasal sinuses film 41 and gingiva tissue 44 at this cortex bone 42 of this nasal sinuses 4.Fig. 1 (A) has illustrated that also a perforation 45 is exposed to nasal sinuses 4.Fig. 1 (B) illustrates that two otch 43 are fabricated on the gingiva tissue 44 to be used in a nasal sinuses and raises during treatment carries out.
Fig. 1 (C) illustrates and uses a dental tool 1 to raise a nasal sinuses film and to fill the bone graft thing.Especially, Fig. 1 (C) illustrates that the nasal sinuses film of a dental tool 1 raises tail and colludes 2 smooth curved terminal part 21, inserts a kerf 43 to cut nasal sinuses film 41 partly from this cortex bone 42 in upper jaw nasal sinuses 4.Advance explanation with reference to Fig. 2 is more detailed after the dental tool 1.Refer back to Fig. 1, upper jaw nasal sinuses 4 can comprise sinunasal originally, or does not have the space, nasal sinuses cave of perforation, and also is to be cut open nasal sinuses film space 8 between nasal sinuses film and the cortex bone 42.The person of advancing, bent back ends portion 21 can be used to the nasal sinuses film 41 of folding this incision and be covered in the perforation 45.
This record embodiment explanation utilizes a dental tool to raise a nasal sinuses film and fills the bone graft thing, but the really not so restriction of other embodiment.For example, one or polydonita section instrument also can according to disclose cut the nasal sinuses film and or folding this nasal sinuses film and gingiva tissue cover the principle of a perforation 45 and use.
Hookup 1, Fig. 1 (D) illustrate that the nasal sinuses film raises tail and colludes this smooth curved terminal part 21 of 2 and insert a kerf 43 further raising nasal sinuses film 41 from cortex bone 42, and increase the size in nasal sinuses film space 8.Fig. 1 (E) illustrates that the nasal sinuses film raises tail and colludes this smooth curved terminal part 21 of 2 and insert another otch 43 so that another partly separates from the cortex bone 42 of this upper jaw nasal sinuses 4 with nasal sinuses film 41, and raises this nasal sinuses film 41.Under the method, nasal sinuses film 41 different parts can be cut open from cortex bone 42, and another nasal sinuses film space 8 can be produced.This cuts and folding program can be undertaken by a part of around the continuous edge perforation 45 or all nasal sinuses films.The person of advancing, Fig. 1 (E) illustrate and fold one first part that one second of nasal sinuses film 41 partly surpasses this perforation and covers this nasal sinuses film that it is the incision among Fig. 1 (C) and folds.
Fig. 1 (F) illustrates that two of nasal sinuses film 41 raise and partly are connected to together.In certain embodiments, a plurality of parts of nasal sinuses film 41 can be sutured in together; But other embodiment may be connected with tissue in other schemes and still belong to disclosed principle.Cover perforation and be sutured in together with the nasal sinuses film, this upper jaw nasal sinuses 4 seals space, upper jaw nasal sinuses cave once again.
Fig. 1 (G) colludes a peripheral channelization terminal part 31 of 3 with (H) bone graft thing tucker tail of explanation dental tool 1, is used to pick up bone graft constituent 5, and this bone graft constituent 5 is filled in space in this upper jaw nasal sinuses 4.In certain embodiments, bone graft constituent 5 can be that spongiosa bone matrix group becomes thing, in order to reduce the chance of damaging nasal sinuses film 41.In addition, more can be utilized more than a kind of bone graft constituent of pattern.For example, in Fig. 1 (H), a spongiosa bone matrix group becomes thing to be placed on earlier that this is folding and sew up by nasal sinuses film and the gingiva tissue, and a granule bone transplantation group becomes to be adjacent to this spongiosa bone matrix group by package after the thing 6 and to become thing.
Be used for raising the dental tool of a nasal sinuses film and filling bone graft with reference to 2, one in figure, according to demonstration comprised one handle 1, a nasal sinuses film raise tail collude 2, and a bone graft thing compressor tail collude 3.At this embodiment, handle 1 is that a rod element is to make things convenient for dentist with hand grip.This nasal sinuses film raises tail, and to collude 2 be to dwindle the prolongation element, extends from an end of handle 1, and have a diameter and a smooth curved terminal part 21 that is about 2mm, suitablely raises nasal sinuses film 41 to insert upper jaw nasal sinuses 4, as the explanation of reference Fig. 1.And bone graft thing compressor tail colludes 3 and can come down to a L type rod element, extends from handle 1 other end, and has a peripheral channelization terminal part 31, in order to fill bone graft thing 5 in these upper jaw nasal sinuses 4 inside, so remembers.In certain embodiments, the nasal sinuses film raise tail collude 2 and bone graft thing compressor tail collude 3 can the titanium coating layer coating.
After bone graft thing 5 is packed into upper jaw nasal sinuses inner space, one reorganize and outfit take root and 9 can be inserted into, as shown in Figure 3.When the bone graft constituent will form bone and be connected in this cortex bone, a root of planting body 9 can be inserted into darker in relatively t, for example about 8mm, guarantee to insert plant body 9 high stability to add and corona further combined with one.
It can be multistage serious perforation.Can select the nasal sinuses recovery technique according to the serious progression of perforation.For example, serious perforation can be divided into Pyatyi, with corresponding processing technology.
For example, losing at the tooth of the upper jaw (maxilla) Background Region will be along with the time causes bone along alveolar ridge bone (alveolar ridge) atrophy.As if this can make plants body and implants in this zone, must rebuild enough bone height earlier.To the scheme in the early time of this condition, involve a side window (lateral window) " nasal sinuses increases (sinus lift) ".Existing a kind of ridge portion scheme increases method based on nasal sinuses, and production method compared to the side window mouth, with less complication, wound is little, healing time is short, is finished nasal sinuses and increased.There are two to pierce through ridge bone major technique now to enter the nasal sinuses film.One is crushing alveolar ridge bone, known cutting bone operation technology (osteotomy technique).Another technology is to drill through the alveolar ridge bone with hydraulic pressure nasal sinuses compress technique.In case connect this alveolar ridge bone, have multiple modification method to be used for cutting the nasal sinuses film.These methods are utilized different instruments and material for example bone, nasal sinuses lifter, bubble, collagen protein, nasal sinuses compressor, nasal sinuses scraper and cutting bone operation.The nasal sinuses perforate membrane is a potential obstacle, when any type of nasal sinuses of execution strengthens program, must be avoided or handle, and the ridge bone enters or the side enters otherwise can run through.
Whether be pre-existing in, perhaps produce during program, nasal sinuses perforation can cause short-term or secular complication, and should handle as quickly as possible.Via the perforation classification, one group of rule can be produced to continue, when implementing these programs according to the perforation classification.This will allow odontologist to determine and this standard program of execution conversely, with the healing of promotion nasal sinuses film and patient's holistic health.In existing example, the classification of nasal sinuses perforate membrane is mainly via the separation size of soft and sclerous tissues and degree and be formulated.Perforation can be divided into Pyatyi, and every grade has himself seriousness and demand program.
In first order perforation, the sustainable bone graft of a doctor and do not need separate procedure.For example, a first order perforation can be defined by being less than 2mm length, does not typically cause concern.Under first order perforation as the current implementing definition, the sustainable bone graft of a doctor and the implantation of taking root, but should note enlarging this perforation.Under this perforation grade, via improving this nasal sinuses, this perforation will fold above itself and seal, and this perforation should not have the quilt of influence to cure.
In the perforation of the second level, a nasal sinuses film folding can be utilized.According to existing example, second level perforation involves a perforation greater than 2mm but less than 5mm.The perforation of one second level can be repaired and not need to postpone the placement that bone graft or is taken root.The perforation of this type is to cause during a treatment wound exodontia (traumaticextraction) maybe ought raise a nasal sinuses the most commonly, and the sufferer with extremely thin mucosa (very thin mucosa) may take place.In order to repair second level perforation, a doctor can leniently cut the film near 5 to 10mm around the cortical bone head edge.In case finish, this film can be by self folding gentle simultaneously raising.After folding this film itself and gentle the raising, the bone graft material can be placed in this nasal sinuses film space.Utilize the bone graft material with the consolidation film, will suitably seal one the perforation and allow one to plant the body program.
The perforation of one third level can involve one and delay film casing technology (delayed membrane casingtechnique).Example according to this, third level perforation are torn the nasal sinuses film fully with one and are formed.A large amount of nasal sinuses perforation is normally pulled out via a tooth when execution one nasal sinuses raises or is caused via unexpectedly piercing through this nasal sinuses film.Perforation with such size, a doctor may punch this cortex bone and drill into this nasal sinuses with proficiency.This scheme is created the hole of a homogeneous on this bone, allowing predictable therapeutic outcome, and in cutting bone operation treatment back safety enter this nasal sinuses film space again.Then, repair third level perforation and involve this perforated seat of sealing, and allow about three weeks of treatment, and the granulation tissue (granulation tissue) of gingiva tissue (gingival tissue) in this punched areas and in the cutting bone operation seat grown up.In case this organizes molding, this seat can be reopened, and a division thickness otch can be caused, in order to create a flap tissue (flap), with the deep and inner granulation tissue of gingiva tissue exposure that comprises.Under the method, surpass three period in week the nasal sinuses film and the gingiva conjunctive tissue should cure and the formed connected granulation tissue that is connected to.Afterwards, the nasal sinuses film can leniently be raised with the bone graft material, and one plants body and can be implanted in this nasal sinuses film space.
Typically, suffering from first and second and the three grades of perforation that ought as above be remembered will repair during original program, and the 4th and the Pyatyi perforation be after perforation has taken place and typically attempted healing.The 4th and Pyatyi perforation normally during the exodontia complication or repeatedly attempt producing when nasal sinuses raises failure.
In fourth stage perforation, nasal sinuses film thickness division sleeve technology (split thickness sinusmembrane casing technique) can be utilized.Typically, fourth stage perforation exposes just like bone Dou Kou infection (bony antra-oral communication), and only this soft tissue is complete.One nasal sinuses film thickness division sleeve technology is to be similar to one " delay technology (delayed technique) " but a difference is arranged.Especially, replace and implement a final cutting bone operation and wait for this cutting bone operation with healing, nasal sinuses film thickness division sleeve technology involves utilizes this cutting bone operation seat to be used as normal healing.This technology is delay technology basically but can not postpone, and is fit to repair a nasal sinuses film of having bored a hole, and its length is enough to make organizes grow into tooth alveolus (toothsocket) or cutting bone operation.This scheme involves produces a division thickness otch, creates a gingiva tissue lobe, reaches this healing organization internal of exposure.Afterwards, this gingiva tissue and nasal sinuses film can raising with the bone graft material by gentleness.
One level V perforation is usually from the result who seriously pulls out complication, or multipunching is from repeating to attempt to implement the result that a nasal sinuses raises, and cortex bone and gingiva tissue can not seal in treatment.One level V perforation can connect (complete antra-oral communication) and classify via a complete Dou Kou, its size range on diameter from extremely several centimeters of pin holes.In level V perforation, gingiva tissue will be grown in this opening, and it will prevent that bone or nasal sinuses film from sealing this wound naturally.In order to repair this pattern perforation, one " depression technology (invagination technique) " can utilize referring to Fig. 1 puts down in writing.
It is graphic to continue, and Fig. 4 shows that a specific embodiment is used for the flow chart of paranasal sinus repairing method 400.At first, as square 410 indications, the gingiva tissue that method 400 is included in around the nasal sinuses perforate membrane is made a kerf.
In certain embodiments, this bent back ends portion of dental tool and this bone graft thing tucker can the titanium coatings.At other a kind of embodiment, it is 2mm that this bent back ends portion can have a diameter.In this example, this paranasal sinus repairing method 400 involve on gingiva tissue make a kerf from this nasal sinuses perforate membrane near 2mm.
Secondly, method 400 comprises eclipsed nasal sinuses film and adjacent gingiva tissue is connected from these nasal sinuses perforate membrane both sides, as indicating 450.In certain embodiments, this covering nasal sinuses film can together be sewed up this gingiva tissue of these nasal sinuses perforate membrane both sides and be connected.
Afterwards, method 400 comprises that filling a bone graft constituent is adjacent to this eclipsed nasal sinuses film, and wherein this bone graft constituent forms and cortex bone articulating bones, is enough to place one and plants the tooth body, as indicating 460.In certain embodiments, fill a bone graft constituent and can comprise further that filling one first spongiosa bone transplantation group becomes thing to be adjacent to this nasal sinuses film; And, fill one second granule bone transplantation group and become thing.
