NCT ID: NCT04873635 Completed - Missing Teeth Clinical Trials

Expectation and Satisfaction of Implant Rehab After Jaw Surgery

Start date: August 2003
Phase:
Study type: Observational

Objective: The aim of this prospective study was to investigate the patient-reported outcome measures (PROMs) of implant-supported prostheses (ISP) among patients who had excised pathological jaw lesions. Material and Methods: Patients who met the inclusion/exclusion criteria in a dental teaching hospital were recruited. Data pertaining to sociodemographic factors, conditions requiring surgery, surgical procedures and related complications, and types of ISP were collected. Patients' expectation and satisfaction to the ISP including oral health, self-perceived appearance, speech, chewing ability, oral comfort and ease of cleaning were assessed using the visual analogue scale (VAS, 0-100) and global transitional scale/judgement (Likert scale). Data were analysed using t-test and chi-square tests at the significance level α=0.05.

NCT ID: NCT04856319 Recruiting - Tooth Loss Clinical Trials

The Effect of Pre-operative Single Dose Antibiotic Prophylaxis on the Post-operative Implant Success

Start date: September 1, 2022
Phase: N/A
Study type: Interventional

There is no consensus on antibiotic prophylaxis in dental implant applications, and its necessity is controversial. Current reports on antibiotic use are insufficient. Also, other than antibiotic prophylaxis, data that may affect the post-operative situation such as the patient's gender, age, smoking, duration of surgery, length of the operation field, flap design have not been evaluated comprehensively. This study aims to evaluate post-operative complications, implant success, and implant stability in 50 individuals: preoperative single dose of 2 g amoxicillin + clavulanic acid (25) and placebo (25).

NCT ID: NCT04855084 Completed - Tooth-loss Clinical Trials

Occlusal Relationship Assesment of Monolithic Zirconia FDPs

Start date: May 24, 2018
Phase: N/A
Study type: Interventional

To analyze in vivo occlusal accuracy and occlusal adjustment requirement, a cross-over clinical trial was designed. Two 3-unit tooth-supported posterior FDPs were planned to be made for each patient's single missing tooth gap, one with complete analog workflow (control group) and the other complete digital workflow (test group). The analog workflow aims for a porcelain fused to metal (PFM) FDP whereas the digital workflow aims for 3-unit monolithic Zr FDP. PFor half of the restorations, digital impression was planned to be taken first and to be followed by analog impression. As for the occlusal adjustment, in half of the study sites monolithic Zr FDPs were planned to be tried-in first, followed by metal-ceramic FDP and vice versa. One investigator (DK) was assigned to prepare the restoration sites and deliver the FDPs. All monolithic Zr and all metal-ceramic FDPs were designed and fabricated by the same experienced dental technician. One investigator (HL), that was not involved in the treatment intervention was assigned to make the 3D analysis of the volumetric occlusal adjustment amount.

NCT ID: NCT04841213 Completed - Tooth Loss Clinical Trials

Dental Implants Rehabilitation in Patients With Vitamin D3 Imbalance

Start date: April 10, 2021
Phase: N/A
Study type: Interventional

Interventional retrospective prospective randomized clinical trial (RCT) in parallel groups. The sample size is 384 patients with loss of teeth and vitamin D imbalance. All patients will undergo or underwent dental implantation after additional investigations which reveal vitamin D imbalance (<30 ng/ml or <75 nmol/l). The 1 group will include 192 patients who will be or were operated on with dental implants after stabilization of vitamin D level with a help of an endocrinologist. The 2 group will include 192 patients who will be or were operated on during the treatment of vitamin D imbalance prescribed by the endocrinologist. The possible difference between groups can be considered the change of dental implants survival time and bone resorption level depending on the level of vitamin D and treatment time by the endocrinologist.

NCT ID: NCT04838184 Active, not recruiting - Tooth Loss Clinical Trials

Short Implants in Edentulous Mandible

Start date: April 19, 2015
Phase:
Study type: Observational

Main aim of this study was to assess survival rates of short implants with a length of 4 mm in the edentulous mandible after 1, 3, and 5 years.

NCT ID: NCT04827693 Completed - Periodontitis Clinical Trials

The Cortical Shield for Facial Bone Reconstruction

Start date: January 3, 2019
Phase:
Study type: Observational

To evaluate a novel technique of bone regeneration and simultaneous implant placement in severely damaged sockets.

NCT ID: NCT04779203 Completed - Tooth Loss Clinical Trials

Study Comparing Osseodensification With Standard Drilling

OD/SD
Start date: July 27, 2020
Phase:
Study type: Observational

The purpose of this study is to examine how Osseodensification, a well-defined bone preparation procedure utilizing special densifying burs (a tool to prepare bone) compares to the standard drilling procedure utilizing regular bone drills, to possibly enhance dental implant healing.

NCT ID: NCT04741906 Recruiting - Cancer Clinical Trials

Outcome of Dental Implant Therapy in Patients Treated With Antiresorptive Medication

Start date: August 1, 2017
Phase:
Study type: Observational [Patient Registry]

Aim of the study is to examine the feasibility of dental implant insertion in patients receiving high, adjuvant and low dose > 4 years.

NCT ID: NCT04741594 Completed - Missing Teeth Clinical Trials

Osseodensification and Implant Survival and Success

Start date: July 1, 2021
Phase: N/A
Study type: Interventional

Approximately 40 implants from patients seeking treatment at the University of Oklahoma, College of Dentistry will be recruited for this study. Osteotomies will be prepared using the osseodensification technique and implants will be placed immediately after. The implants will be from a single manufacturer (Roxolid® SLA® Bone Level Tapered; Straumann®, Institut Straumann AG, Basel, Switzerland). Volumetric analysis of alveolar ridge will be studied using intra-surgical direct measurements and CBCT imaging. A custom stent will be fabricated to standardize the clinical and radiographic measurements at 2mm, 3mm, and 4mm apical to the alveolar crest. Changes in peri-implant bone density will be analyzed on standardized periapical and bitewing radiographs, using the ImageJ software (National Institute of Health, Bethesda, Maryland, USA). Implant stability quotient (ISQ) values will be recorded with a resonance frequency analysis system (Osstell®, Gothenburg, Sweden). Calibrated examiners will assess implant survival and biological or restorative complications and failures. Sites will be evaluated throughout osseointegration and one year after final restoration is delivered.

NCT ID: NCT04713800 Recruiting - Clinical trials for Jaw, Edentulous, Partially

Two-unit Cantilever Implant Prostheses Made of Monolithic Zirconia or PFM

Cantilever
Start date: July 28, 2021
Phase: N/A
Study type: Interventional

The aim of is to compare the survival rate and technical outcomes of cantilever implant-supported fixed denture prosthetics (cFDPs) made either out of monolithic zirconia bonded to a titanium base in a digital workflow, or porcelain fused-to metal using a gold abutment in a conventional workflow. In addition, biological outcomes, wear patterns, PROMs and time efficiency will be recorded. The null hypothesis is: the reconstruction type does not influence the survival rate and technical outcomes of 2-unit implant-supported cFDP.
