About this study
Official title: Comparison of Positional Accuracy in Dental Implant Placement Between Conventionally Used Guide Pin and 3D Printed Surgical Guide Developed From CBCT
This is a randomized controlled study that aims to compare the accuracy between full-guided with guide-pin-assisted free-hand dental implant surgeries. The basis of evaluation in each case is the comparison of the preoperative digital plan with the actual postoperative status.
Read the detailed description
Dental implant surgery is a treatment that replaces damaged or missing teeth with artificial teeth that are aesthetically and functionally similar to natural teeth. For a successful implant surgery, it is necessary to use digital planning software in conjunction with a cone-beam CT scan and a custom-made 3D-printed surgical guide. In developing countries like Bangladesh, surgical guide-assisted dental implant surgery is absent. Doctors attend implant surgeries relying on their visual assessment from x-ray images or CBCT data. They need to cut the outer soft tissue, expose the bone, and use a guide pin to confirm the direction and location. Then they perform implant surgery following the hole created by the guide pin, similar to free-hand surgery. But the overall procedure is still highly invasive and has low accuracy.
Free-hand implant surgeries are still in practice everywhere. The application of a guide pin has been observed in some places to enhance the situation. A guide pin helps an operator recognize the position and angle of an alveolar bone when forming an implantation hole in the alveolar bone to insert an implant into the alveolar bone. Doctors insert a guide pin to the implant site with minimal incision and then confirm the desired direction and location with a radiographic image. However, we need a proper clinical evaluation to compare fully-guided surgeries to guide-pin-assisted surgeries to understand the accuracy of both processes.
The accuracy of the pre-planned 3D-printed surgical guide is well established. Introducing dental software and guided surgery has already achieved higher acceptance in implant surgery. Several patients from several privileged parts of the world benefit from surgical guides. But the usual design convention includes intraoral scanner data with CBCT. However, intraoral scanners are still unavailable in many dental hospitals. The study is designed to address the precision of dental implant surgeries worldwide, especially where the intraoral scanner is not present. In our research, we will focus on partially edentulous patients. And our design procedure will not be dependent on intra-oral scanner data. As partially edentulous patients are higher in number and CBCT machines readily available in hospitals, this study can open up a way to address the scarcity of intra-oral scanner data to avail a large number of implant patients with an effective guide. The success rate of this study will encourage us not only to prioritize guided surgeries over free-hand practices or guide-pin-assisted surgeries but also to significantly impact the execution of implant surgeries in developing countries.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Surgical GuideDevice
For this case, after the patient is given anesthesia, the guide will be placed on the teeth. All the drillings will be performed through the guided path. There will be no need for raising flap according to flapless surgery. At the end of the operation, the operation site will be checked and hemostasis will be provided. The operator will record the operation in the source documentation. 2 ± 1 days later, a postoperative CT scan will be taken. A follow-up visit will be due 14 ± 2 weeks later, after the osseointegration period.
Guide-pin-assisted Freehand surgeryProcedure or surgery
The regular protocol of the implant surgery will be followed. Before the surgery begins, the patient will be given anesthesia to ensure they are comfortable and pain-free during the procedure. Doctors will go through the digital planning to understand the desired angulation. Then the bony bed will be prepared raising flap from targeted area. Then a guide-pin will be inserted by drilling and through radiographic image the direction will be confirmed. Following the hole of the guide-pin, the implant will be inserted. At the end of the operation, the raised flap will be sewn and hemostasis will be provided. The operator records the operation in the source documentation. 2 ± 1 days later, a postoperative CT scan will be taken. A follow-up visit will be due 14 ± 2 weeks later, after the osseointegration period.

Questions about this trial
What is this clinical trial studying?
A study testing Surgical Guide and Guide-pin-assisted Freehand surgery in people with Partially Edentulous Mandible and Dental Implantation, run by Dhaka Dental College and Hospital at 1 site in Bangladesh.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 26 Sep 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Bangladesh. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Dr. Md Al-Amin Sarkar, BDS, FCPS (Prosthodontics) (+8801715748863, dr.sarkar.bds@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Angular deviation (time frame: 3 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05983718, which also lists 16 linked publications.
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?
