Digital Analysis Using 3D Intraoral Scanner on Gingival Contour Changes Following the Roll Flap Technique

The study aimed to evaluate changes in buccal gingival contour following implant surgery using the simultaneous roll technique on Seibert class I defects, as determined by 3D intraoral scan data. Three patients requiring implant placement were recruited, and implants were placed using the roll flap technique. Digital impressions of the surgical site were obtained with a 3D intraoral scanner before surgery, after suture removal, and 4 months postoperatively. The results showed an overall increase in buccal gingival contour, with a maintained increase in soft tissue contour after 4 months. The study concluded that 3D scanning is a suitable method for assessing small changes in gingival contour, making it ideal for evaluating these changes. The roll flap technique was also found to effectively enhance the buccal gingival contour and soft tissue appearance around the implant collar.
