Hard and Soft Tissue Outcomes of Vestibular Socket Therapy Using Magnesium Membrane Versus Cortical Lamina in the Esthetic Zone.
Hard and Soft Tissue Outcomes of Vestibular Socket Therapy Using Magnesium Membrane Versus Cortical Lamina for Type II Extraction Sockets in the Esthetic Zone: A Randomized Clinical Trial
This randomized clinical trial aims to compare two membrane materials used in Vestibular Socket Therapy (VST) technique during immediate implant placement in Type II extraction sockets in the esthetic zone.
A total of 30 patients will be randomly allocated to receive VST using either a biodegradable magnesium membrane or a cortical lamina membrane. Both groups will receive immediate implant placement and xenogeneic bone graft.
The study will compare changes in facial bone dimensions, soft tissue volume, implant stability, pink esthetic score, patient satisfaction, surgical time, and postoperative complications over a 6-month follow-up period.

Medidas de resultado primarias
Medida de resultado |
Medida Descripción |
Periodo de tiempo |
|---|---|---|
|
Facial Bone Dimensional Changes
Periodo de tiempo: Immediately after surgery (T0) and 6 months (T6)
|
CBCT scans obtained immediately after surgery (T0) and at six months (T6) will be superimposed using OnDemand3D software.
The following parameters will be assessed: facial bone thickness at the crestal level, facial bone thickness at the middle level, facial bone thickness at the apical level, and facial bone height.

Medida Descripción |
Periodo de tiempo |
|---|---|---|
|
Soft Tissue Volumetric Changes
Periodo de tiempo: Baseline and 6 months postoperatively
|
Assessed by superimposition of intraoral scan STL files obtained at baseline and 6 months postoperatively.
|
Baseline and 6 months postoperatively
|
|
Patient-reported Esthetic Satisfaction
Periodo de tiempo: 6 months postoperatively
|
Assessed at 6 months using a 100-mm Visual Analog Scale (VAS), where 0 indicates complete dissatisfaction and 100 indicates complete satisfaction with the esthetic result.
|
6 months postoperatively
|
|
Surgical Time
Periodo de tiempo: During the surgical procedure
|
Recorded in minutes from the start of the surgical procedure until completion.
|
During the surgical procedure
|
|
Postoperative Complications
Periodo de tiempo: 1 week, 1 month, 3 months, and 6 months postoperatively
|
Recorded throughout the follow-up period and evaluated at 1 week, 1 month, 3 months, and 6 months postoperatively for the occurrence of membrane exposure, wound dehiscence, infection, graft loss, and implant failure.
|
1 week, 1 month, 3 months, and 6 months postoperatively
|
|
Implant Stability
Periodo de tiempo: Immediately postoperatively, 3, and 6 months postoperatively.
|
Assessed using radiofrequency analysis (RFA) using an Osstell Mentor Device.
A SmartPeg will be attached to each implant, and resonance frequency measurements will be recorded in four directions (every 90°).
The obtained values will be expressed as Implant Stability Quotient (ISQ) scores, and the mean ISQ value for each implant will be used for statistical analysis.
The Implant Stability Quotient (ISQ) ranges from 1 to 100, with higher scores indicating greater implant stability.
|
Immediately postoperatively, 3, and 6 months postoperatively.
|
|
Pink Esthetic Score (PES)
Periodo de tiempo: 6 months postoperatively.
|
The Pink Esthetic Score (PES) assesses peri-implant soft tissue esthetics using seven parameters, each scored from 0 to 2, for a total score of 0-14.
Higher scores indicate better esthetic outcomes.
Assessed using standardized clinical photographs.
|
6 months postoperatively.
