Exposed Threads Management During Dental Implant Placement: Case Reports
Objectives: Two clinical cases involving patients aged 53 and 35 years were referred by their dentists to the periodontology department at the dental clinic of dentistry in Monastir for dental implant placement. Both patients presented compromised ridges, and exposed threads during the implant placement procedure. Simultaneous regeneration was performed, and successful long-term results were achievedThe aim of this work is to present these cases and discuss the criteria for choosing between a staged approach and simultaneous regeneration in similar clinical situations.
Methods: During implant placement, thread exposure was especially observed in post-extraction sites or where alveolar ridges are compromised. The lack of bone adjacent to an implant is considered as a bony defect, and several techniques have been proposed to promote defect fill with newly formed bone. These defects may range from very small lack of marginal bone to large areas of denuded implant surfaces as we will present.
The main indications for treating these osseous defect are to increase implant success rates, avoid subsequent soft-tissue problems, and enhance the esthetic outcome. For this purpose, the use of different methods and materials has been advocated. Simultaneous regeneration procedures, using bone grafts and barrier membranes, are usually necessary in such situations to correct peri-implant defects and/or to augment surrounding tissues.
Results: Performing guided bone regeneration during implant placement has consistently yielded successful results.This approach has not only met the challenge effectively but has also saved valuable time by eliminating the need for staged procedures.
Conclusions: Before proceeding with dental implant placement and simultaneous regeneration, it is essential to conduct an initial clinical and radiological evaluation. This evaluation helps us identify cases where it is more likely to obtain excellent primary stability in the optimal three-dimensional position, ensuring successful treatment outcomes with high predictability and minimal complications. However, in cases where primary stability is unattainable due to insufficient bone volume, a staged approach becomes must be considered.
