Contour Augmentation Simultaneous to Immediate Implant Placement in Compromised Sockets: A Retrospective Study.

Area of Science:

• Dental Implantology
• Periodontology
• Oral Surgery

Background:

• Immediate implant placement (IIP) in compromised extraction sockets presents challenges for achieving optimal esthetic and functional results.
• Contour augmentation techniques are crucial for managing bone and soft tissue deficiencies in these scenarios.

Purpose of the Study:

• To evaluate the effectiveness of contour augmentation using guided bone regeneration (GBR), with or without subepithelial connective tissue grafts, in conjunction with IIP in compromised fresh extraction sockets.
• To assess clinical, radiographic, and patient-reported outcomes (PROs) for this combined surgical approach.

Main Methods:

• A retrospective case series analyzed 49 implants in 28 patients undergoing IIP with GBR in non-molar sites.
• Connective tissue grafts were used for thin soft tissue phenotypes or high esthetic demands.
• Cone-beam computed tomography (CBCT) assessed bone thickness and bone crest levels; follow-up was at least 12 months post-prosthesis.

Main Results:

• High implant survival and peri-implant health (93.9%) were observed.
• Favorable mean crestal bone levels (0.08 ± 0.21 mm) and significant buccal and palatal bone thickness were achieved.
• Facial bone was present coronal to the implant shoulder in 91.8% of cases, with positive patient-reported outcomes.

Conclusions:

• Contour augmentation via GBR combined with IIP in compromised sockets yields favorable clinical, radiographic, and patient-reported outcomes.
• This approach effectively addresses bone and soft tissue deficiencies, enhancing implant success rates and patient satisfaction.
