Alveolar Bone Loss
Conditions
Interventions
This is a two-arm, double-blind, randomized controlled clinical trial. The experimental group consists of the extraction of a posterior tooth (premolar or molar) with the placement of a non-resorbable

Eligibility
Age
18 Years to No maximum
Inclusion criteria
Inclusion criteria: Be over 18 years of age; both genders; voluntarily agree to participate in the study and sign the Informed Consent Form; have no allergies or intolerances to polypropylene; require extraction of a posterior tooth (premolar or molar); have no fistulas; not be undergoing orthodontic treatment; not use removable partial dentures that have support on the teeth adjacent to the tooth to be extracted; not be taking medications that interfere with bone remodeling processes (e.g., bisphosphonates); have adjacent teeth to the tooth to be extracted
Exclusion criteria
Exclusion criteria: Express interest in withdrawing from the study by revoking consent; present ridge characteristics that make membrane placement unfeasible after extraction; fail to attend the tomographic exams at the scheduled times; present complications after the extraction that require surgical reintervention or the prescription of antibiotics
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Outcome name: Dimensional change of the alveolar ridge (bone thickness and height; Metric/assessment method: Measurement of the width and height of the alveolar ridge by means of cone beam computed tomography (CBCT), at times T0 (preoperative), T1 (immediately or up to 24 hours after the intervention) and T2 (3 months postoperative). Standardized measurement using tomographic guide with hyperdense marker; Assessment time: T0 (preoperative), T1 (up to 24 hours after extraction), T2 (3 months after surgery) | — |
Secondary
| Measure | Time frame |
|---|---|
| Outcome name: Alveolar ridge bone volume; Metric/assessment method: Volume difference measured by intraoral scanning, with superimposition of STL files obtained at suture removal (E1) and after 3 months (E2). Software assessment with images of regions with dimensional alteration. Assessment time: E1 (7 to 10 days after surgery), E2 (3 months after surgery);Outcome name: Postoperative discomfort reported by participants; Assessment metric/method: 10 cm Visual Analogue Scale (VAS) for pain, applied immediately after suturing (D0), 24h after (D1), between 7 to 10 days (D2) and 3 months (D3). The distance between the beginning of the line and the marking will be measured in millimeters; Assessment time: D0 (immediately after surgery), D1 (24h), D2 (7 to 10 days), D3 (3 months) | — |
