About this study
Official title: Clinical Comparison of Pontic Site Development With Connective Tissue Graft Using Modified Pouch Technique Versus Pouch Technique: A Randomized Controlled Clinical Trial
The study will be formed on two groups : the control group and the test group For both groups base line impressions will be taken before the surgery and a free gingival graft will be harvested from the palate and deepithelialized to obtain the free connective tissue graft then In the control group: the free connective tissue graft will be inserted through crestal pouch previously prepared using split thickness flap.
In the test group The free connective tissue graft will be slided through apical vertical incision in the pontic area previously tunneled.
Post operative casts will be obtained by taking impressions after three months and six months to evaluate the volumetric changes in the pontic area.
Read the detailed description
Study settings: Study is to be conducted in the Oral Medicine and Periodontology department, Faculty of Dentistry - Cairo University, Egypt. Patients are to be selected from the outpatient clinic of the department of Oral Medicine and Periodontology-Cairo University Pre-surgical phase: Patients will be initially examined. All patients received oral hygiene instructions, and non-surgical periodontal treatment will be performed if necessary. At baseline, clinical periodontal measurements including plaque Index, bleeding on probing (BOP) , probing depth (PD) and clinical attachment level (CAL) will be recorded at teeth adjacent to the gap using a Williams's periodontal probe. Impressions will be taken using high viscosity impression material. Models will be cast in dental stone and used as the baseline reference for volumetric measurements. De-epithelialized connective tissue harvesting: The palatal sites will be anaesthetized with 0.3 ml of a solution of 4% Articaine and 0.001% Adrenalin. Graft harvesting will be performed by basic surgical techniques ). A rectangular shaped piece of mucosa will be harvested from the area of the hard palate by a split-thickness dissection. The graft will then be de-epithelialized, and the connective tissue graft will be used. Surgical site preparation for either control or intervention group: 1- Local anesthesia (2% lidocaine, 1: 100 000 epinephrine), incisions will be placed over the crest of the ridge reaching to alveolar bone. 2- Papillae will include in the incision line only when there is a loss of papillary height. 3- A deep supraperiosteal soft tissue pouch will be prepared by sharp dissection extending apically to the mucogingival line and to the neighboring teeth mesio-distally. 4- A rectangular shaped free gingival graft will be harvested from the contralateral palate using split thickness dissection.
Control group: -The graft will be de-epithelialized and the connective tissue graft will be inserted into the pouch that will be previously prepared at the recipient site and will be secured with two non-resorbable sutures at the labial and the palatal aspect. - Provisional restoration will be temporary cemented. -. Patient will be recalled after 14 days for suture removal.
Test group: Modified pouch technique -. De-epithelialization of the area that resembles in position and size the emergence profile of the pontic -. Tunnel preparation in the soft tissues buccal to the defect region using split thickness flap preparation. - Preparation of the pouch extends in a lateral direction to adjacent teeth and in an apical direction beyond the mucogingival line in order to ensure sufficient flap mobility. -. Flap preparation will also include elevation of the interproximal tissues lateral to the edentulous site. - Vertical releasing incision in the alveolar mucosa apical and distant to the defect will be done. -. The graft will be then drawn using positioning sutures. -. Provisional restoration will be temporary cemented on both abutments then double-crossed sutures are used for the fixation of the buccal soft-tissue complex, including the connective tissue graft. 8. Patient will be recalled after 14 days for suture removal. After the surgical volume augmentation procedure, clinical periodontal measurements will be recorded, impressions will be retaken and models will be cast at 3 and 6 months postoperative, In both control and intervention groups.

What is being measured
The primary outcome is the main question the study is designed to answer.
volumetric changes at the pontic site
To evaluate the volumetric changes between the baseline and 6 months postoperatively all the cast stone models will be digitized using lab based optical scannerDigital cast models will be reproduced resembling different time points during treatmentSuperimposing the different models of the same case using the best fit algorithm by taking the tooth surfaces as references The area of pontic site will be defined by the mesial and distal papillary midline, the mucogingival line, and the alveolar crest So any volumetric changes between digitalized superimposed casts can be measured.
Measured: 6 months
Secondary outcomes (1)
Postoperative pain - through Visual Analogue Scale
Pain score reported by the patient directly through Visual Analogue Scale score (between 0 and 10. 0: no pain, 1: minimal pain, 5:moderate pain, 10: severe pain) VAS will be recorded at day 14
Measured: 14 days

volumetric changes at the pontic site (time frame: 6 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Mar 2019; AzTrials last refreshed its copy on 29 Oct 2026.
