Soft tissue augmentation around dental implants using connective tissue graft or less invasive approaches

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This investigator-initiated, single-center, randomized trial compares three peri-implant soft tissue augmentation approaches in adults with a thin peri-implant phenotype: subepithelial connective tissue graft, submerged tenting abutment, and sub-crestal implant placement. The goal is to determine which technique most effectively increases soft tissue thickness while potentially reducing morbidity compared with the standard grafting method. Participants are adults requiring a single posterior mandible implant, with specific anatomic and health criteria, and will be followed to assess tissue outcomes and implant performance. The study addresses whether less invasive approaches can provide comparable tissue stability and clinical success to the traditional grafting option.

Why it matters

Who can join: the full rules

Inclusion Criteria:

* Adults aged 20 years or older.
* Partially edentulous patients requiring a single dental implant in the posterior mandible.
* Thin peri-implant soft tissue phenotype (\<2 mm).
* Horizontal alveolar ridge width of at least 6 mm.
* Vertical bone height of at least 10-12 mm, confirmed radiographically.
* Adequate interarch restorative space for implant-supported restoration.
* Medically healthy (American Society of Anesthesiologists \[ASA\] Physical Status I or II).
* Good oral hygiene.
* Able and willing to provide written informed consent.

Exclusion Criteria:

* Local pathological lesions affecting the surgical site.
* Smoking.
* Pregnancy or breastfeeding.
* Alcohol abuse or parafunctional habits that may compromise implant survival or wound healing.
* Medical or local conditions that could interfere with osseointegration, soft tissue healing, or study participation
