Tooth Restoration Basics


Tooth restoration is the process of repairing or replacing tooth structure that is decayed, damaged or missing. There are a variety of restorative materials that can be used for this purpose, such as composite resin, amalgam or porcelain.


The procedure for restoring severely damaged teeth must be based on consistent scientific evidence to reduce dental error and improve prognosis. This includes establishing clinical criteria and guidelines for restoration repair versus replacement.

Direct Restorations

Direct restorations are fabricated within the mouth and do not involve the use of a dental laboratory. They include dental fillings, inlays, onlays and veneers. Unlike indirect restorations which are fabricated in a dental laboratory and then placed in the mouth, direct restorations are completed during a single dental appointment. This makes them more cost-effective than indirect restorations. However, direct restorations have some limitations that must be considered by clinicians and patients.

Historically, many different materials have been used in the direct restoration of teeth. The most popular are amalgam and resin composite. Amalgam is an amalgamation of silver and mercury, while composite is a tooth-colored resin that bonds to the remaining tooth structure. The use of resins for the direct restoration of the teeth has increased due to their esthetic appearance and improved biomechanical properties.

The most important consideration when deciding to place direct restorations is the condition of the patient’s teeth and supporting structures. The presence of significant decay, large cracks or chips or extensive tooth wear can make placing a direct restoration risky.

Other factors such as the patient’s lifestyle and oral hygiene regimen should also be considered before recommending direct restorations. If these factors are taken into account, the longevity of a direct restoration can be significantly improved.

Direct restorations are the most commonly used dental treatment in the world. They are a safe, reliable and effective restorative option for patients with minor to moderate decay, cracks and chips, or discoloration of the teeth. However, the aging of the patient’s dentition, as well as poor oral hygiene and diet can accelerate the deterioration of the natural teeth.

It is recommended that patients visit the dentist for regular checkups to detect and treat small problems before they become major issues. This will help to prevent advanced decay, and 서울치과 the need for more invasive indirect restorations.

Long-term clinical studies on the survival of direct posterior composite and amalgam restorations are needed to determine their longevity. The results of these studies will help to optimize the products and techniques available to the clinician and improve patient care.

The longevity of direct restorations can be improved by limiting the amount of tooth structure exposed to abrasion during preparation, utilizing low-viscosity adhesives and by eliminating air bubbles between the tooth and the restoration. It is also necessary to regularly evaluate the restorations using objective criteria, ideally as part of a systematic protocol. The material, equipment and clinical technique employed should be precisely documented to enable a long-term clinical audit of minimally invasive restorative procedures. The knowledge gained from these audits will promote further research and development in the field of direct restorations. This will ultimately lead to a more biologically compatible restorative approach to dentistry.
