Autotransplantation of teeth (ATT): An alternative treatment for replacing natural teeth

Abstract

Background/Aim: Autotransplantation of teeth (ATT) has been performed a long time ago and recently gained high clinical acceptance. ATT aims to restore hopeless teeth with natural ones regaining aesthetics and function. ATT is the technique of transplanting embedded, impacted, or erupted teeth from one site into another in the same individual under controlled conditions. In comparison to conventional methods of restoring lost teeth, it offers manybenefits, especially for children and young adults. On the periodontal aspect, it includes bone regeneration and re-establishment of the alveolar ridge, so it can be effective in regions with severe bone loss.

This is a case series of autotransplantation of partially or fully erupted third molars with complete root formation into the extraction site of grossly decayed, unrestorable first or second molars on the same side of the same arch with regular follow-ups showing excellent periapical healing, tooth stability and periodontal regeneration with the aid of Cone-beam CT before and after the treatment.

The survival and success rates of tooth transplantation can exceed 90% after mid-term and long-term follow-up periods. Many factors can influence the results of ATT. It must be performed with a complete understanding of biological concepts connected to success. It is critical to keep the periodontal ligament of the transplant intact. Ahigh success rate can be achieved if the cases are properly selected and treated. Chances of root resorption especially the replacement resorption/ankylosis are there. However, ATT should always be considered as a good treatment modality in feasible cases.

Isolation in endodontics

Abstract

The use of rubber dam is considered the standard of high-quality dental care. It provides protection for the patient and facilitates dental treatment for the dental practitioner. It helps in the elimination of microorganisms which is an important factor for successful root canal treatment. In its turn, providing effective contamination control measures leads to prevention of root canal system reinfection. (Rubber dam is a mandatory adjunct and is universally acknowledged particularly during endodontic and aesthetic treatment. Its usage has been advocated and encouraged by many authors to adopt in routine practice including operative dentistry field (Ahmad, 2009))

The use of rubber dam also provides enhanced access and visibility to the working area, absolute dryness of the field, better control of cross-infection, prevents soft tissue contact with chemicals, and improves the treatment efficiency and long-term outcomes. However, with the recent advancement in clamps design, shape, and function, the use of rubber dam in endodontics has been made easy.

Many Challenges have been reported for its lack of use, including concerns over patient acceptance, the time required for application, cost of equipment and materials, insufficient training, difficulty in use, and low treatment fees. Though, failure to use a rubber dam has been shown to influence the treatment outcome and places the patient at risk of swallowing or aspirating materials and instruments used during operation.
