Peri-implant keratinized mucosa (PIKM) augmentation refers to surgical procedures aimed at increasing the width of PIKM. Consensus reports emphasize the necessity of maintaining a minimum width of PIKM to ensure long-term peri-implant health. Currently, several surgical techniques have been validated for their effectiveness in increasing PIKM. However, the selection and application of PIKM augmentation methods may present challenges for dental practitioners due to heterogeneity in surgical techniques, variations in clinical scenarios, and anatomical differences. Therefore, clear guidelines and considerations for PIKM augmentation are needed. This expert consensus focuses on the commonly employed surgical techniques for PIKM augmentation and the factors influencing their selection at second-stage surgery. It aims to establish a standardized framework for assessing, planning, and executing PIKM augmentation procedures, with the goal of offering evidence-based guidance to enhance the predictability and success of PIKM augmentation.

Objective To compare the suture bridge (SB) and conventional double-row (DR) suture in the repair of full-thickness rotator cuff tear.Methods From May 2013 through July 2016,48 patients with full-thickness rotator cuff tear were randomly divided into 2 even groups (n =24).SB group was repaired using the SB technique while DR group using conventional DR technique.The 2 groups were compared in terms of operation time,postoperative shoulder function scoring and incidence of re-tear.Results All the patients were followed up for 8 to 24 months (average,15.3 months).In DR group,the visual analogue scale (VAS) scores decreased from preoperative 6.3 ± 2.3 to 1.0 ± 0.4 at the last follow-up,the America Shoulder and Elbow Surgeons (ASES) scores increased from preoperative 49.3 ± 8.5 to 90.0 ± 2.5 at the last follow-up,and the Constant scores increased from preoperative 58.7 ± 12.5 to 88.1 ± 4.0 at the last follow-up.In SB group,the VAS scores decreased from preoperative 6.0 ± 1.9 to 0.9 ± 0.8 at the last follow-up,the ASES scores increased from preoperative 50.2 ± 6.2 to 89.5 ± 3.4 at the last follow-up,and the Constant scores increased from preoperative 57.3 ± 7.5 to 90.0 ± 3.2 at the last follow-up.All the comparisons showed a significant difference between preoperation and the last follow-up (P ＜ 0.05),but an insignificant difference between the 2 groups (P ＞ 0.05).SB group used significantly less operation time (74.5 ± 19.0 min) than DR group (86.5 ± 21.0 min),and reported significantly lower incidence of re-tear (4.2％) than DR group (25.0％) (P ＜ 0.05).Conclusions In arthroscopic repair of full-thickness rotator cuff tear,SB technique shows few therapeutic advantages over conventional DR technique,but the former needs less operation time and leads to lower incidence of re-tear.
