3D-Printed PLA Guide Versus Resin Guide in Mandibular Molar Implant Placement (CGIIPMM-PLA-MR)
Computer Guided Immediate Implant Placement in Mandibular Molars Using Patient Specific 3D Printed Polylactic Acid Guide Versus Modified Resin Guide
Przegląd badań
Status
Szczegółowy opis
This randomized clinical trial compares two tooth-supported computer-guided surgical guide systems for immediate implant placement in mandibular molar extraction sockets: a patient-specific 3D-printed polylactic acid (PLA) guide system and a modified resin guide system. Preoperative CBCT and digital intraoral scans were used for prosthetically driven virtual implant planning and fabrication of the surgical guides.
Implant positioning accuracy was assessed by comparing the planned and actual implant positions using preoperative and postoperative CBCT datasets. Angular deviation, coronal deviation at the implant platform, and apical deviation were recorded.
Primary implant stability was assessed immediately after implant placement using Implant Stability Quotient (ISQ) measurements obtained with an Osstell device. Surgical time was recorded from seating of the surgical guide and initiation of osteotomy until completion of implant insertion.
The study was designed to compare the performance of the two guide systems in immediate mandibular molar implant placement.

Eksperymentalny: patient specific 3d printed PLA guide
Immediate implant placement in mandibular molar extraction sockets using a patient-specific tooth-supported 3D-printed PLA surgical guide system.
Preoperative CBCT and digital intraoral scans were used for prosthetically driven virtual implant planning and guide fabrication.
The guide was fabricated from PLA according to the planned implant position.
Following atraumatic tooth extraction and socket preparation, the guide was seated and osteotomy preparation was performed through the guide's guiding channel according to the planned trajectory, followed by immediate implant insertion.
Primary implant stability was assessed using an Osstell device and Implant Stability Quotient (ISQ) measurements.

Aktywny komparator: Modified Resin guide
Immediate implant placement in mandibular molar extraction sockets using a tooth-supported modified resin surgical guide system.
Preoperative CBCT and digital intraoral scans were used for prosthetically driven virtual implant planning and guide fabrication.
The guide was fabricated from light-cured surgical-guide resin according to the planned implant position.
Following atraumatic tooth extraction and socket preparation, the guide was seated and osteotomy preparation was performed through the guide's guiding channel according to the planned trajectory, followed by immediate implant insertion.
Primary implant stability was assessed using an Osstell device and Implant Stability Quotient (ISQ) measurements.

accuracy of implant position
Ramy czasowe: Assessed within 1 week postoperatively, following acquisition of the postoperative CBCT scan.
|
Accuracy of implant placement will be evaluated by comparing the planned implant position from the preoperative digital plan with the actual implant position obtained from the postoperative CBCT scan.
Deviations will be assessed in three dimensions, including angular deviation (degrees), coronal deviation (platform) (mm), and apical deviation (mm).
Measurements will be performed using specialized implant-planning software by superimposing the preoperative and postoperative datasets.
Lower deviation values indicate greater agreement between the planned and actual implant positions.
|
Assessed within 1 week postoperatively, following acquisition of the postoperative CBCT scan.

primary implant stability by osstell
Ramy czasowe: Measured immediately at the time of implant placement during the surgical procedure.
|
Primary implant stability will be assessed using an Osstell device, which measures Implant Stability Quotient (ISQ) values through resonance frequency analysis.
A SmartPeg will be attached to the implant, and ISQ readings will be taken in two perpendicular directions (buccolingual and mesiodistal).
Higher ISQ values indicate greater mechanical stability.
The mean ISQ value for each implant will be recorded and used for analysis
|
Measured immediately at the time of implant placement during the surgical procedure.

surgical time
Ramy czasowe: Assessed intraoperatively, measured during the surgical appointment, and recorded immediately after surgery
|
Surgical time will be recorded to evaluate the procedural efficiency of guided immediate implant placement.
Time will be measured from seating of the surgical guide and initiation of osteotomy until completion of implant insertion.
The total duration will be recorded in minutes.
