“…Based on this data, it may be reasoned that probing depth resolution following osseous surgery is complete by 3 months. This finding is similar to that suggested by Deas et al . in an investigation of surgical crown lengthening around anterior teeth.…”

Background:The purpose of this study is to examine the relationship between immediate post-surgical flap position and subsequent probing depth measurements following osseous surgery. Methods:Twenty-four patients treatment planned for osseous surgery after completion of initial therapy and re-evaluation were enrolled. Pressure molded stents were fabricated to serve as a reference for probing depth and relative attachment level measurements prior to surgery. After osseous recontouring was completed, flaps were sutured and compressed, and bone sounding measurements were made as designated by the stent. Patients returned at 3-and 6 months for repeat measurements of probing depth and attachment level.Results: Twenty-four patients completed surgical treatment and follow-up measurements with a total of 402 treated sites. A statistically significant moderate correlation between immediate post-surgical bone sounding measurements and subsequent probing depth was found at 6 months (R = 0.56, P < 0.001). There was no significant difference between this correlation at 3 and 6 months. The probability of having 6 month probing depth ≤3 mm was 93.5% when the surgical flap was placed within 3 mm of the alveolar crest (286/306 sites) as opposed to 50% when the surgical flap was >3 mm away from the alveolar crest (48/96 sites). Interproximal sites were significantly more likely (P < 0.01) to have probing depths > 3 mm at 3 and 6 months. Conclusions:Results suggest a statistically significant relationship between immediate post-surgical flap placement and subsequent probing depths. Positioning the surgical flap more closely to the alveolar crest when performing osseous surgery resulted in shallower probing depths at 3 and 6 months.

“…Moreover, a different pattern in the healing response between different tissue biotypes was observed, with the coronal regrowth at interproximal and buccal/lingual sites being significantly more pronounced in patients with a thick tissue biotype than in patients with a thin tissue biotype. The tendency for a coronal shift of the soft‐tissue margin during healing was also confirmed by Perez et al , Arora et al , and Deas et al , on studies with 6 months of follow‐up. In particular, Arora et al and Deas et al related the tissue rebound to the postsurgical flap position, observing greater growth when flaps were positioned closer to the alveolar crest.…”

These findings underline the importance of a presurgical evaluation by the clinician, and the extent of the ostectomy should be considered according to the tissue biotype.…”

Crown lengthening is one of the most common surgical procedures in periodontal practice. Its indications include subgingival caries, crown or root fractures, altered passive eruption, cervical root resorption and short clinical abutment, and its aim is to re-establish the biologic width in a more apical position. While the procedure in posterior areas of the dentition has been thoroughly investigated, crown lengthening performed for esthetic reasons in the anterior areas is still a matter of debate and an evidence-based technique is not available. This paper provides accurate descriptions of the surgical and restorative phases of the esthetic crown-lengthening procedure by answering the following questions: what is the ideal surgical flap design? how much supporting bone should be removed? how should the position of the flap margin relate to the alveolar bone at surgical closure? and how should the healing phase be managed in relation to the timing and the position of the provisional restoration with respect to the gingival margin?
