Clinical Trial Summary

The aim of the present study is to evaluate the health of immediately placed dental implants in aggressive periodontitis patients versus those placed in periodontally healthy individuals in the maxillary esthetic zone.

Clinical Trial Description

Aggressive periodontitis is an enigmatic periodontal disease that characterized by massive and undeterminable periods of tissue destruction. It gets along well to young individuals with successive periods of disease activity. Aggressive bone destruction with limited plaque and calculus deposits usually detected. According to microbial theory, Aggregatibacter actinomycetemcomitans (A.a) and P. gingivalis (P. G) were claimed for such a disease. Patients of aggressive periodontitis have disturbed esthetic and masticatory function problems.

After wards, microbial theory was modified to enroll the genetic background that can be the cause behind the developed body resistance. Although the importance of the genetic treatment to improve the body response, it was totally dismissed during the routine periodontal work attributable to high cost effectiveness of the needed genetic analysis especially in developing countries.

Further researches tried to explain the cause behind the impaired body response. Impaired functions of the immune cells and the massive amounts of catabolic cytokines such as IL-1, IL-6, Il-17, TNF- α and prostaglan¬din E2 (PGE2) are usually released during the active periods of the disease. On the other hand, matrix-metalloproteinases are destructive enzymes that released in an uncontrollable manner. Host modulators were suggested to control the released of the destructive agents.

Immediate implant placement provides an efficient modality that shortens the dental management period. The aim behind immediate implant placement is the proper implant positioning to counteract the advanced bone resorption following extraction.

Periodontitis is considered an important risk factor for peri-implantitis. The pre-existing periodontitis must be treated prior to implant placement in order to avoid the bacterial accumulation in the periodontal lesions regardless the type of periodontitis. Local and systemic supportive therapy is strongly recommended in order to reduce the microbial colonies and post-operative bone loss.

Higher rate of implant failure (peri-implantitis) has been reported in immediately placed implants when compared with the delayed conventional technique. The failure rate markedly increased with the immediate placement of implants in patients with history of periodontitis especially the aggressive form. ;
