Erythritol vs Ultrasonic Scaler Prophylaxis Systems on Dental Implants With Crowns Made by Different Materials

Start date: March 1, 2024
Phase: N/A
Study type: Interventional

The aim of the study is to assess which prophylaxis methods is the most suitable for peri-implant hygiene between erythritol and ultrasonic scaler with peek inserts. A randomized clinical trial will be conducted on the patient. Patients will be randomly divided into two groups: - Erythritol group: erythritol with a particle size of ~14 µm will be used for 5 seconds (AIRFLOW® PLUS EMS) - Ultrasonic scaler group: a piezoelectric handpiece with peek inserts (Mini Piezon EMS; PI EMS) will be used. Different subgroups will be defined according to the material of the dental crown of the related implant. The oral hygiene session will be carried out every 6 months (2-years follow-up; 6 sessions), after instruction and motivation of the patient, completion of the clinical chart with the recording of the Probing Depth (evaluation in mm of the peri-implant sulcus taken by a periodontal probe; 4 surfaces of the gingival margin are detected: vestibular, palatal/lingual, mesial, distal), Bleeding on Probing and Plaque Index.

NCT ID: NCT06250114 Completed - Clinical trials for Dental Implant Failed

Retreat or Replace: Retrospective Investigation on a Cohort of Local Patients

Start date: January 12, 2008
Phase:
Study type: Observational

Introduction: To evaluate the survival and success rate of premolars with a previous root canal treatment which underwent to non-surgical retreatment or to extraction and implant replacement. Materials and methods: Patients visiting in the Clinical Endodontic Section of the School of Dentistry (University of Bologna) were eligible for the study. Out of these patients, those with previously root canal treated premolars fulfilled the inclusion criteria. Teeth were considered retreatable and restorable (Endo group) or not retreatable and not restorable (Implant group) on the basis of clinical and radiographical examination. Each patient was included in an annual recall programme and final evaluation was performed after 8 years. Clinical parameters were recorded. Differences in baseline characteristics between the two treatment groups were assessed using logistic regression analysis with clustered standard errors. Results were expressed for each variable as odds ratios (ORs) of implant rehabilitation to root canal retreatment with 95% confidence intervals (CIs). Survival and treatment success for the two study groups were estimated using the Kaplan-Meier method. The association of treatment group with time to event was assessed using Cox proportional hazard regression analysis with clustered standard errors to allow for intragroup correlation within teeth belonging to the same patient. Results were expressed as hazard ratios (HRs) of experiencing the study event among implants as compared to root canal retreatments with 95% CIs.

NCT ID: NCT06240416 Not yet recruiting - Clinical trials for Dental Implant Failed

Autogenous Particles Harvesting During Implant Surgery

Start date: March 15, 2024
Phase: N/A
Study type: Interventional

The aim was to compare the osteoblast activity and osteogenic potential of autogenous bone particles harvested using three different techniques, determine the most advantageous method of collecting autogenous bone particles. Bone particles were harvested during dental implant surgery using low-speed drilling and high speed drilling. After the osteoblasts were cultured, cell proliferation, migration, mineralization, transcription of osteogenesis-related genes, secretion of osteogenesis-related proteins, and osteoinductive protein content in the bone particle matrix were evaluated

NCT ID: NCT06206499 Recruiting - Peri-Implantitis Clinical Trials

Laterally Rotated Flap for Soft Tissue Augmentation Around Maxillary Loaded Osseointegrated Dental Implant

Start date: April 4, 2024
Phase: N/A
Study type: Interventional

Peri-implant mucositis is one of the most common peri-implant diseases. It was reported in more than 20% of the subjects rehabilitated with dental implants (Lee et al. 2017; Rodrigo et al. 2018; Wada et al. 2019). Furthermore, a significant association was found between peri-implant mucositis, and smoking, implant maintenance and peri-implant soft tissue characteristics (Wada et al. 2019). Soft tissue quality and volume of the peri-implant mucosa are considered important factors in the prognosis of osseointegrated implants. Linkevicius et al. showed that if its soft tissue thickness was less than 2 mm, crestal bone loss might occur (Linkevicius et al. 2009). In addition, when soft tissue width was evaluated, a wider soft tissue band was related to minimal bone remodeling (Linkevicius et al. 2015). Lin et al. reported in a systematic review and meta-analysis that a lack of keratinized tissue (KT) around osseintegrated implants was associated with plaque accumulation, peri-implant tissue inflammation, soft tissue recession and attachment loss (Lin et al. 2013). Moreover, recent studies established the need of a minimal band of 2 mm of KT around osseointegrated implants, and showed that a band less than 2 mm was associated with more brushing discomfort, plaque accumulation, tissue inflammation and marginal bone apical displacement, concluding that a KT>2 mm had a protective effect on peri-implant tissues (Souza et al. 2015, Perussolo et al. 2018, Monje et al. 2019). Furthermore, peri-implant tissue diseases have also been related to an irregular compliance in situations of lack of KT (Monje et al. 2019). In the presence of peri-implant horizontal and/or vertical soft tissue deficiencias, soft tissue augmentation has been considered a priority, even prior or instead of bone augmentation (Burkhardt et al. 2008, Zucchelli et al. 2013).

NCT ID: NCT06123221 Recruiting - Clinical trials for Dental Implant Failed

SINUS FLOOR WITH OSSEODENSIFICATION OR LATERAL WINDOW

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

This study will compare patient-reported outcomes, as well as the type and incidence of complications, and bone marginal loss after 12 months in implants installed using the transcrestal approach (tSFE) with an osseodensification system (performed according to the protocol by Huwais et al. 2018), or installed simultaneously using the lateral window technique (lSFE) with sinus lift. A blind, randomized, controlled clinical trial will be carried out with individuals over 18 years old, and with single tooth loss in the posterior maxilla, where the residual bone height (RBH) is 3 to 5 mm. The tSFE will be performed with osseodensification burs (Densa Bur, Versah, USA) using a counterclockwise motion, associated to synthetic biomaterial (hydroxyapatite and beta-tricalcium phosphate). The lSFE technique will require the sinus to be filled with the same biomaterial as the group using the other technique, and the antrostomy to be covered with a polydioxanone-based membrane. The patient's post-operatory perceptions will be evaluated by self-administered questionnaires quantifying social and professional isolation, physical appearance, duration and changes in quality of life, eating and speech, diet variations, and sleep deficiency for 2 weeks after the procedure. Pain will be assessed with the visual analogue scale (VAS). Immediately after prosthetic rehabilitation, cone beam tomography will be performed. Controls at 6 and 12 months will be performed. In these images, the marginal bone level in relation to a fixed reference point on the implants (upper part of the platform) will be measured mesially and distally in each implant, using a specific program (ImageJ - version 1.49v / NIH software - Bethesda, MD, USA). Generalized estimating equations will be used to compare the two treatments overtime. The significance level used will be 0.05.
