The adjacent inlay for tooth restoration can prevent food impaction by restoring the contact relationship between two impaction adjacent teeth, and can also restore the loss of periodontal tissues such as gingival atrophy alveolar bone absorption and the like caused by food impaction due to various reasons. In the restoration, since the area of food impaction is relatively small, the tooth preparation amount is small in use. And only the damaged tooth surface is needed to be polished, the healthy tooth tissue is not polished, and the healthy tooth tissue can be kept, so that the damage to the tooth tissue is reduced.

In some embodiments of the present embodiment, the first contact body 2 and the second contact body 3 are both in a crescent structure, an extrados surface of the crescent structure is fixedly connected with the main body 1, and an intrados surface 4 of the crescent structure can be attached to the dental restoration surface. The intrados 4 of the crescent-shaped structure can be adhered to the tooth restoration surface to be attached through an adhesive, so that the adjacent inlay for tooth restoration is tightly connected with the adjacent teeth. The size of the adjacent inlay for tooth restoration flexibly changes according to the size of an intraoral abutment, and according to the average numerical value of a dental crown, the height of the adjacent inlay for tooth restoration is generally 8-10mm, the mesial-distal diameter is the connecting line distance of the midpoints of the extrados of the crescent structures arranged on the two sides of the main body 1, the connecting line distance is generally 4-6mm, the face, close to the face, of the adjacent inlay for tooth restoration is called a buccal face, the corresponding adjacent inlay face is a buccal wall, the side, close to the tongue, of the lower tooth is called a lingual wall, the upper tooth is called a palatal wall, the buccal wall is generally 2-3mm in width, and the thickness can be 1-1.5 mm.
