简要总结
Patients were randomly distributed into two groups (G1 and G2), all patients were treated by a submerged dental implant protocol and free gingival graft (FGG) harvested from the palate as follows:
- Group 1 (G1), received the FGG two months before implant placement.
- Group 2 (G2), received the FGG at the time of second-stage surgery (i.e. at the time of healing abutment placement).
All periodontal and radiographic assessments were done by the same operator who was neither involved in the evaluation nor the distribution process. The operator did all the evaluation steps and was completely blinded to the treatment protocol.
详细描述
In this investigation, a randomized clinical trial was employed. The patient's randomization was completed by one of the department's senior residents, who was not involved in the trial and was unaware of any relevant treatment plan. A computer-generated randomization list used a randomization table to perform the randomization (SPSS v23.0). Patients were randomly distributed into two groups (G1 and G2), all patients were treated by a submerged dental implant protocol and FGG harvested from the palate. All patients received a thorough description of all procedures involved in the study. Signing a written consent was mandatory for being enrolled in the study. Complete medical and dental histories were recorded for all patients and complete clinical intraoral and extraoral examinations were done for all patients.
Selected patients were questioned about the cause and time of extractions, whether extractions were because of periodontal disease, dental decay or other causes. Previous experiences with dental procedures were also discussed. Intraoral photographs were taken to record the existing condition of teeth and mucosa before implant placement.

结局指标
主要结局
Keratinized Mucosa Width (KMW)
时间窗: Baseline, 1 month, 3 months, 6 months, and 9 months
Measurement Method: The assessment of KMW involved measuring from the alveolar ridge zenith to the muco-gingival junction (MGJ) using a calibrated periodontal probe. Unit of Measure: Millimeters (mm)
Soft Tissue Thickness (STT)
时间窗: Baseline, 1 month, 3 months, 6 months, and 9 months
Measurement Method: STT was determined 1.5 mm apical to the soft tissue margin (STM) using a short anesthesia needle or endodontic micro-opener with a silicon stopper. Unit of Measure: Millimeters (mm) Measurement Procedure: The needle was inserted perpendicular to the mucosal surface, through the soft tissues with light pressure until a hard surface was felt. The silicon stopper was placed in tight contact with the soft tissue surface, and the penetrated part was measured on an endodontic ruler. Measurements were rounded to the nearest half of a millimeter.
Graft Shrinkage
时间窗: 1 month, 3 months, 6 months, and 9 months
The decrease in the size of the graft at each follow-up time was compared to the baseline. size. It was presented in percentage
