NCT ID: NCT06404385 Completed - Dental Implant Clinical Trials

Accuracy of Static Computer-assisted Implant Surgery in Distal Free-end Scenarios

Start date: September 11, 2012
Phase: N/A
Study type: Interventional

Technological advances have influenced the approach to implant treatment. One of the fields presently experiencing rapid development is static computer-assisted guided surgery (sCAIS), which allows transfer of the virtual implant planning to the mouth of the patient, based on the use of a surgical guide. In sCAIS there is a deviation between the virtually planned implant position and the actual position of the implant placed during surgery. A recent review analyzed only fully guided implants and recorded a mean coronal horizontal deviation (CHD) of 1.12 mm (standard deviation [SD] = 0.08), a mean apical horizontal deviation (AHD) of 1.41 mm (SD = 0.1), a mean vertical deviation (VD) of 0.12 mm (SD = 0.23), and a mean angular deviation (AD) of 3.58º (SD = 0.2). The aim of the present study was to compare the accuracy of CAD-CAM and conventional guides in candidates for distal free-end implant treatment, and to analyze the effects of possible confounding factors inherent to the patient or the surgical technique employed.A prospective, controlled and blinded quasi-experimental study was carried out involving 27 patients with 76 implants distributed into two groups according to the surgical guide manufacturing approach used: conventional (control group [CG]) or CAD-CAM (test group [TG]). The implants were planned virtually with the planning software, and the surgical guides were manufactured. Fully guided implant placement was carried out, and the deviations were measured along with other secondary variables as potential confounding factors.

Accuracy of Guided Ridge Splitting With Simultaneous Implant Placement

Start date: August 2, 2023
Phase: N/A
Study type: Interventional

Assessing whether is there a difference between computer-guided ridge splitting and conventional technique with simultaneous implant placement in patients with maxillary width deficiency.

NCT ID: NCT06277076 Completed - Dental Implant Clinical Trials

Accuracy of Computer- Guided Implant Surgery in Partially Edentulous Patients.

Start date: January 28, 2023
Phase:
Study type: Observational [Patient Registry]

The dental implant placed freehand with a digital planing is vastly increasing. The accuracy between the planned and the placed implants still not well determined. Between a single implant and a full mouth rehabilitation, the precision is very wide. A precision scale must be settled according to each indication in order to offer the clinician a safety and a predictability for his procedures.

NCT ID: NCT06250621 Completed - Dental Implant Clinical Trials

Manual or Digitally Guided Surgical Technique for Replacing Single Tooth Edentulism by Means of Sub-crestally Placed Implants. A 3-year Parallel Randomized Clinical Study on Marginal Bone Levels Stability

Start date: January 10, 2020
Phase: N/A
Study type: Interventional

The aim of the present prospective study was to investigate after a 2-year of follow-up any influence of the surgical technique, manual or digitally guided, on peri-implant marginal bone levels stability in implants placed 1 mm sub-crestally. Patients were treated by means of platform-switched implants provided with a 5 degrees internal conical connection and supporting single screw-retained fixed crowns. Marginal bone level (MBL) measured at prosthesis installation (t0) at 1 (t1), 2 (t2) and at 3 years of follow-up visit (t3) were considered. MBL change from t0 to t3 was investigated. The distance between the implant neck and the first radiographically detected bone to implant contact was considered to evaluate the bone loss. Two groups were considered: Test Group (GD) for implant sites treated with a digitally guided surgery procedure. Control Group (FH) for implants surgically placed without digitally guided surgery, respectively. All the procedures were performed by an experienced operator. Additionally, for both groups MBL changes were correlated to different supra-crestal soft tissue height (STH) amounts: less than 3 and ≥ 3 millimeters, respectively. Peri-implant soft tissue parameters such as probing depth (PPD), modified Sulcus Bleeding Index (mBI) and modified Plaque Index (mPI), were assessed for all the restorations included.

Computer Guided Versus Freehand Dental Implant Surgery

dental implant
Start date: June 1, 2022
Phase: N/A
Study type: Interventional

This study's goal is to evaluate the efficacy of traditional rehabilitation with freehand implant implantation of partly or totally edentulous patients utilizing flapless or mini-flap procedures vs. 3D implant design software and specialized surgical templates.

NCT ID: NCT06138392 Completed - Dental Implant Clinical Trials

Long-term Study in Early Loaded Hydrophilic Surface Implants

Start date: September 1, 2020
Phase:
Study type: Observational

Objective: To assess the clinical outcomes and patient satisfaction of early loaded implants with a hydrophilic, moderately rough surface for partially edentulous patients after a follow-up of 8.5 to 9.5 years. Materials and methods: A prospective observational single-centre study involving 15 patients with single, delayed placement and early loaded implants in the posterior area was performed. Clinical and radiographical parameters, including biological and technical complications and patient satisfaction, were assessed.

Volumetric Analysis of Maxillary Sinus After Guided Lateral Sinus Lift Procedure

Start date: December 29, 2020
Phase: N/A
Study type: Interventional

The purpose of this study is to present a guided lateral window sinus lift (GLSL) procedure with the aid of a fully digital workflow using surgical templates for window osteotomy preparation and implant placement.

NCT ID: NCT06127576 Completed - Dental Implant Clinical Trials

Biomechanical Informational Effect of Innovative Double or Triple Dental Abutment-implant: Case-series

Start date: September 1, 2009
Phase:
Study type: Observational

Objective: The aim of this case series study is to present the rationality and scientific evidence of a new design for a Double and Triple abutment with their specific new concept of Biodynamic Optimized Peri-implant Tissue (BOPiT). Methods: The innovative design of these abutments with a paraboloid geometry was based on BOPiT, simultaneously involving the principles of mechanobiology, biotensegrity, and mechanotransduction. Thus, individuals rehabilitated with different extents of edentulous spaces using the innovative double and triple abutments on osseointegrated dental implants are included in this case series. The double and triple abutments support 2 or 3 dental crowns on a single implant, respectively. Clinic and radiographic examinations are presented at T1 (loading after 4 months of the implant insertion surgeries with the appropriate metalloceramic prostheses) and T2 [final examination with a follow-up time ≥ 3 to 12 years (average of 7.2 years)].

NCT ID: NCT05948254 Completed - Dental Implant Clinical Trials

Utilized Scan Body Technique For Triple Function

Start date: May 11, 2022
Phase: N/A
Study type: Interventional

A triple function scan Body were done on healed dental implant, thus simplifying the workflow for full arch cases and reducing the number of visits to only 3 visits. In this technique, scan bodies were utilized for implant position scanning, facial scan alignment and as stoppers for jaw relation capturing as scan bodies were used as stoppers for jaw relation registration.
