Inlays are restorations embedded in the dentition to restore its form and function
The development of inlay restorations is influenced by the material and the relationship between dentistry and economic level. Inlays have been used clinically since 1856, and they are basically used in developed countries for restoration of dental defects. But currently in our country because of the filling (fillings), with the expansion of the indications for crown-type restorations (braces), dental restorations most of the time do not meet the design gold standard.

Defective larger live pulp teeth, there are economic conditions should do gold alloy inlays, rather than fillings (except for anterior teeth affect the aesthetics, you can design resin, porcelain inlays), and do not just make a full crown (braces), should do inlays to preserve the live pulp, save the tooth. The inlay restoration will not be damaged for many years.
General characteristics of inlays.
Inlay Filling (filling)
Anatomical morphology of the occlusal surface of the tooth Easy to form Difficult
Easy to form adjacent contact relationship Difficult
Biomechanical properties of the material (marginal fit) Good Fragility of the margins
Resistance to abrasion Good Good Good
Operation Complex Simple
Restoration of occlusal function Good Fair or poor
Retention methods Mechanical and adhesive Inverted concave retention
Indications: Consider social, cultural, economic background, health, aesthetic requirements to make permanent bionic restorations.
Comparison of materials: Making inlays of common metals such as nickel complex alloys can cause excessive wear to the teeth in the opposite jaw, resulting in medically induced tooth damage! In addition, the material shrinkage edge does not fit well, and it is easy to produce secondary dental caries.
Material comparison
Ordinary alloy inlay: cheap, poor ductility, easy to wear the teeth in the opposite jaw.
Silver palladium inlays: better ductility than ordinary alloy, metallic color, high fracture strength.
Resin, porcelain inlays: color is more realistic than metal inlays, close to the color of the teeth, super hard material fracture strength and wear resistance is not as good as metal inlays.
Gold alloy inlays: the best ductility! Long-term use of high density, not easy to occur secondary caries (tooth decay again), biocompatible, long-term use of the human body has a health care effect, no side effects, if the design, production is excellent, is a real permanent restoration. The disadvantage is that the price is higher.
Anyone who wants to do filling treatment, if the economic conditions allow, the posterior teeth should do gold alloy inlays. Do inlays consider the resistance and retention of the remaining dentition, inlays should be made for the specific design of the remaining dentition tissue to play a role in protecting the dentition, inlays made abroad also in many cases do not meet the design gold standard! The theoretical and technical level of the dentist’s dental profession and the technician’s production process are important conditions to ensure the high suitability between the inlay and the tooth. Choosing a skilled dentist to be your health care dentist is an important thing for dental patients to prevent the tragic destruction of dental organs!
