Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To compare the static computer-aided implant surgery (s-CAIS) and conventional laboratory-guided implant surgery (c-LIS) in terms of accuracy for single tooth replacement in posterior areas.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

There was still a lack of evidence in randomized clinical studies about the accuracy measurement comparing digital and laboratory workflows with tooth-supported templates for single implant cases in the posterior regions. Therefore, this present study's primary investigation was to perform accuracy measurement comparing digital and laboratory workflows with tooth-supported templates for single implant cases in the posterior regions. The secondary investigation was to find the effect of several factors on the accuracy of implant placement in these areas.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

s-CAIS (static computer aided implant surgery)

For the s-CAIS group, Cone Beam Computed Tomography (CBCT) and full-arch optical scan were performed to provide digital information for implant planning software (coDiagnostix 9, Dental Wings GmbH, Chemnitz, Germany). The virtual implant was set on a three dimensional (3D) virtual jaws according to the prosthetically driven protocol by one postgraduate dentist and was confirmed by one experienced dentist. Static surgical template covering on occlusal part of 4 teeth anteroposteriorly was then fabricated via 3D printing machine (surgical guide resin, Form 2, Formlabs, Somerville, Massachusetts, USA). This surgical template would be used during surgery.

Group Type EXPERIMENTAL

Accuracy measurement

Intervention Type OTHER

Three months following the implant placement, patients were called back to the implant clinic to record the actual implant position with the digital impression technique. Full mouth scans were done by using the intraoral scanner (Trios 3, 3Shape, Copenhagen, Denmark). The surface scans were then exported as an STL file and were imported to coDiagnostiX software. The "Treatment evaluation tool" function tool was used to measure the accuracy of the implant placement which measured the amount of deviation of the placed implant from the planned position. The outcomes were generated into three main parameters.

c-LIS (conventional laboratory-guided implant surgery)

For the c-LIS group, a radiographic template (ORTHO Plast, prominent®, Chonburi, Thailand) was fabricated covering on occlusal part of 4 teeth anteroposteriorly according to diagnostic wax-up on the study model. A radiographic marker (gutta percha) was then filled in the created hole of the template and for used while taking CBCT image to verify marker position.

Next, a study model was scanned by laboratory surface scan (D900m, 3Shape, Copenhagen, Denmark). The STL file was imported to 3D printing devices and the resin model was fabricated (Dental LT clear resin, Form 2, Formlabs, Somerville, Massachusetts, USA).

Next, the same template that had been used for CBCT was used to place implant replicas in a resin model. The position of the implant replicas in the models were assumed as pre-operative planned implant position.
