Definitions
- This invention relates to photopolymerizable & photocleavable resin monomers and resin composite compositions, which feature by its unique balanced overall performance including very low polymerization shrinkage and very low shrinkage stress as well.
- the photoreactive moiety incorporated into such new resin's main frame enable to make the resin and/or the cured resin networks that are based upon such resin photocleavable.
- the polymerization rate of free radical reaction for (meth)acrylate-based resin systems should be substantially reduced since it alter the network formation process and consequently allow the shrinkage stress getting relief significantly.
- the invention also relates to relates to compositions that have exceptionally low curing stress, which are comparable to conventional low stress composite, and have substantial flowability, which is comparable to conventional flowable composite.
- the dental materials from such compositions with such unique property is for use in the dental arts in the treatment of teeth
- Highly cross-linked polymers have been studied widely as matrices for composites, foamed structures, structural adhesives, insulators for electronic packaging, etc.
- the densely cross-linked structures are the basis of superior mechanical properties such as high modulus, high fracture strength, and solvent resistance.
- these materials are irreversibly damaged by high stresses due to the formation and propagation of cracks.
- Polymerization stress is originated from polymerization shrinkage in combination with the limited chain mobility. Which eventually leads to contraction stress concentration and gradually such a trapped stress would released and caused microscopically the damage in certain weak zone like interfacial areas. Macroscopically it was reflected as debonding, cracking, et al.
- a new kind of resin composition is provided.
- a new concept is involved in designing such a new resin composition, which would render the polymerization stress in post-gel stage to a subsequent, selective network cleavage in order to have the stress partially released.
- all of previous arts towards low shrink and low stress are based on the limitation on the shrink and stress formation in general.
- the shrinkage and stress development in cured network system should have two different stages: a pre-gel phase and a post-gel phase. Actually, most efforts of current arts are focussed on the pre-gel stage and some of them were proved to be effective.
- a photopolymerizable and photocleavable resin is proposed and a general molecular constitution is designed. It was expected that such a resin monomer can be polymerized like any other resin monomer but its mainframe is able to be triggered to break upon additional light source such as near UV is blended. This is a typical photocleavable process, but it is its capability to be photopolymerized and embedded into a cross-linked system make it unique. In addition, it also makes possible to avoid regenerating any leachable species through such secondary breakage.
- Photocleavage is nothing new in solid synthesis of peptides, from which new peptides was directed on certain template in designed sequence, then it was cleaved from its template via a subsequent light exposure. There is no chemical contamination with such a process.
- photoacid and photobase could be viewed as extended applications for photocleavage.
- Acidic or basic component is temporally latent to avoid any unwanted interaction with others in the system and they can be released on demand such as light exposure to trigger the regeneration of the acid or base, which then act as normal acidic or basic catalyst for next step reactions.
- thermally removable or photo-chemically reversible materials are developed in order to make polymer or polymeric network depolymerizable or degradable for applications such as easily removing of fill-in polymer in MEMS, thermally labile adhesives, thermaspray coatings and removable encapsulation et al.
- photocleavable dentrimers are explored in order to improve the efficiency for drug delivery. Based on our knowledge, there is no prior art involved photocleavable segment in cured network for contract stress control. However, all of those related arts could be used as a practical base to justify this investigation.
- Dental composite is formulated by using organic or hybrid resin matrix, inorganic or hybrid fillers, and some other ingredients such as initiator, stabilizer, pigments et al so as to provide with the necessary esthetic, physical and mechanical property for tooth restoration.
- polymerization shrinkage from cured dental composite is one of dental clinicians' main concerns when placing direct, posterior, resin-based composite restorations.
- improvements associated with resin-based composite materials, dental adhesives, filling techniques and light curing have improved their predictability, the shrinkage problems remain. In fact, it is the stress associated to polymerization shrinkage that threaten marginal integrity and lead to marginal gap formation and microleakage, which may contribute to marginal staining, post-operative sensitivity, secondary caries, and pulpal pathology.
- a common approach to reduce the polymerization shrinkage of dental composite is to increase the filler loading, especially for posterior restoration.
- the higher viscosity of these highly filled composites may not adapt as well to cavity preparations.
- 1-2 It has been demonstrated that to initially place a flowable composites which, with less filler content, have greater flexibility, could reduce microleakage than direct application of microhybrid and packable composite restorations, 3-4 but this benefit may be offset by the increasing polymerization shrinkage for the flowable composite itself. 5 Therefore, it is also highly desirable to develop low shrinkage, especially low curing stress flowable composite, in order to really reduce microleakage as mentioned above.
- shrinkage can also be reduced by using special filters which allow an increase in filler loading without compromising too much in handling property. Even so, the curing stress from most of flowable composites remains substantially high. Obviously, it is highly desirable to develop flowable dental composition with low curing stress.
- a light responsible moiety should be stable towards standard light exposure process such as visible light curing until additional exposure to specific light with distinguished energy level.
- energy source can be anything other than the standard visible blue light.
- Near UV light would be one of typical examples among the many possible choices.
- compounds derivated from ortho-nitrobenzyl segment or from ⁇ -hydroxyalkylphenone should be ideal candidates for this new class resin monomers that be photopolymerized by visible light and be triggered to be breakable by extra UV light if needed.
- such new resin monomer was formulated with other conventional resin monomers like BisGMA, TEGDMA, UDMA or experimental resin monomer like macrocyclic resin in a variety ratio in order to have overall performance got balanced for the resulting composites.
- other conventional resin monomers like BisGMA, TEGDMA, UDMA or experimental resin monomer like macrocyclic resin in a variety ratio in order to have overall performance got balanced for the resulting composites.
- remarkable low shrinkage, low stress and excellent mechanical property plus the good handling characteristics were demonstrated by those composites based on such new class P&P resin monomers.
- composition of matter that can be polymerized via an energy source, containing portions within the new composition of matter that are reactive to a second energy source.
- the invention also provides a composition of matter that can be polymerized via an energy source, containing portions within the new composition of matter that are reactive to a second energy source and that upon activation of the second source of energy, de-polymerize and/or degrade.
- a composition of matter is also provided that can be polymerized via a first energy source, containing portions within the new composition of matter that are reactive to a second energy source and that upon activation of the second source of energy, de-polymerize and/or degrade without substantially effecting the structural properties of the material polymerized by the first energy source.
- a further composition of matter is provided that can be polymerized via a first energy source, containing portions within the new composition of matter that are reactive to a second energy source and that upon activation of the second source of energy, de-polymerize and/or degrade to elevate stress created during the polymerization of the composition of matter created via the first energy source without substantially effecting the structural properties of the material polymerized by the first energy source.
- composition of matter comprises monomers, prepolymers and/or polymers that can be polymerized via an energy source (thermal, photochemical, chemical, ultrasonic, microwave, etc.), containing portions within the new composition of matter that are reactive to a second energy source (thermal, photochemical, chemical, ultrasonic, microwave, etc.).
- energy source thermochemical, photochemical, chemical, ultrasonic, microwave, etc.
- second energy source thermochemical, photochemical, chemical, ultrasonic, microwave, etc.
- a photopolymerizable and photocleavable resin monomer offers unique combination of low curing stress and good mechanical strength.
- the inventive P&P resin features by incorporating a photoresponsive moiety within the resin monomer and is a (meth)acrylate based resin and capable of being polymerized as any other conventional (meth)acrylate monomers.
- the presence of such a photoresponsive moiety enables P&P resin to polymerize in a way different from those conventional (meth)acrylate monomers. More specifically P&P resin polymerize with a unique curing kinetic, which allow stress relief through the relatively slow curing process without compromising the overall mechanical strength.
- substantially low polymerization shrinkage stress results from P&P resin and P&P resin based composite, as compared to those conventional resin like BisGMA/TEGDMA or EBPADMA, and other conventional composites.
- Typical posterior composites based on the inventive P&P resin and loaded 80-82% (wt/wt) of inorganic fillers offer shrinkage stress of 1.3-1.7 Mpa. They can also demonstrate good mechanical strength.
- the present invention is extended application of P&P resin. It was unexpectedly discovered that an exceptionally low curing stress remained even with lowering filler loading, which paved a way to low stress flowable composite.
- the filler level varies from 1% to 70%, wt/wt, preferably, 10-60%, wt/wt, and more preferable 50-60%, wt/wt.
- the conventional resin monomers can also be incorporated by up to 40-50%, wt/wt with P&P resin, depending upon the nature of such conventional resin monomer and the end use.
- the filler composition can be adjusted as well.
- the present invention provides flowable composites with an exceptionally low polymerization stress of 0.9-1.3 MPa, which is about 60-70% less than that of typical EsthetXflow (3.4 MPa) or Dyractflow (4.6 MPa). More importantly, the new flowable material can still offer moderate mechanical property. This unique property combination regarding low curing stress and handling character enable to be used as dental restoratives like liners, sealants, et al and other application field where curing stress and flowability is critically concerned.
