Intraoral Prosthetic Chin Augmentation With Vertical Incisions

Current methods for chin augmentation often involve external incisions, which can lead to visible scarring and increased postoperative complications. Prior research has shown that intraoral approaches reduce external scarring but may lack precision in prosthesis placement. No prior work had resolved the challenge of achieving accurate positioning while minimizing complications. This gap motivated the development of a new intraoral technique. The anatomical structure of the chin influences surgical outcomes, yet few studies address how incision design affects implant stability. Existing literature highlights the need for improved visualization during implant insertion. The risk of implant displacement remains a concern in current methods. That uncertainty drove the exploration of a novel intraoral approach with vertical incisions.

The aim of this study was to evaluate a new surgical method for chin augmentation using intraoral vertical incisions. This approach aims to improve the accuracy of prosthesis placement while reducing complications. The specific problem addressed is the challenge of achieving stable implant positioning without visible scarring. The motivation stems from the limitations of existing techniques that rely on external incisions. The method incorporates three incisions to enhance surgical control. The study focused on patients with mild microgenia to test the approach's effectiveness. The goal was to assess whether this method could correct chin deformities with fewer complications. The researchers proposed that the intraoral design would allow for better visualization and implant stability.

The surgical approach involved three intraoral incisions: two vertical mucosal cuts and a central observation incision. The V-shaped marking on the prosthesis was aligned through the observation incision. The lateral incisions provided access for implant insertion into a predesigned compartment. The incisions were sutured only if no bleeding occurred during the procedure. The study included 19 patients with mild microgenia, all undergoing this technique. Follow-up periods ranged from 6 to 12 months to monitor outcomes. The placement of the prosthesis was guided by anatomical landmarks. The method was evaluated based on postoperative complications and aesthetic results.

All 19 patients achieved satisfactory chin and facial shape without complications. The V-shaped marking on the prosthesis was clearly visible through the observation incision. The median incision allowed for real-time confirmation of implant positioning. No patients experienced implant displacement during the follow-up period. The bilateral incisions provided stable access for implant insertion. The method reduced the risk of sideways or vertical movement of the prosthesis. The surgical approach minimized postoperative bleeding and scarring. The results suggest this method improves accuracy and reduces complications compared to traditional techniques.

The authors propose that this intraoral technique offers more accurate implant placement. The use of three incisions allows for better visualization and control during surgery. The study suggests this method reduces the risk of implant displacement. The absence of complications in all patients supports the safety of the approach. The V-shaped marking on the prosthesis aids in confirming correct positioning. The method is suitable for correcting McCarthy type I microgenia. The results align with the goal of minimizing postoperative complications. The authors suggest this technique may provide a reliable alternative to existing methods.
