NCT ID: NCT05990088 Recruiting - Missing Teeth Clinical Trials

Comparison Between Conventional and CAD/CAM Complete Dentures Designed Based on Neutral Zone Concept

Start date: June 1, 2023
Phase: N/A
Study type: Interventional

A within-subject cross-over study is done on eight completely edentulous patients to compare two different complete removable dentures. Group I: Heat cured Conventional complete dentures designed based on the neutral zone concept; Group II: CAD-CAM neutral zone complete dentures designed based on the neutral zone concept. Occlusal analysis is done by the T-Scan device, and evaluation of muscle activity is conducted by electromyography at insertion time, two weeks after insertion time, and one month after insertion time.

NCT ID: NCT05689814 Completed - Dentures Clinical Trials

Retention, Stability and Performance Assessment of Denture Fixatives Versus no Fixative Control

RESONATE
Start date: January 30, 2023
Phase: N/A
Study type: Interventional

This clinical investigation will evaluate the effectiveness, tolerability and safety of two denture fixative creams versus no fixative control

NCT ID: NCT04003493 Completed - Oral Mucositis Clinical Trials

LifE Style, Nutrition and Oral Health in Care Givers (LENTO)

Start date: May 15, 2019
Phase: N/A
Study type: Interventional

The LENTO study sample includes the caregivers and their clients living in eastern Finland. The aims of this study are 1. to study the nutritional status, oral health, coping, functional capacity and quality of life 2. to find out how individual nutrition and oral health counseling received for caregivers affect on the nutritional status and oral health of caregivers and their clients 3. develop an operating model to maintain good nutrition and oral health.

NCT ID: NCT03753932 Completed - Quality of Life Clinical Trials

Impact of Fixed Dentures in Head and Neck Cancer (IMFDHAC)

IMFDHAC
Start date: March 1, 2013
Phase: N/A
Study type: Interventional

The purpose of the multi centre study is to evaluate an intervention, which means that patients undergoing radiotherapy for head and neck cancer will receive fixed dentures in accordance with the Public Health Care fee system with regard to well-being and oral health related quality of life. Hypotheses: the intervention will improve oral health related quality of life, general wellbeing, and nutrition in patients treated by radiotherapy, with or without combination of chemotherapy or surgery against head and neck cancer.

Wear Characteristics of Denture Teeth

Start date: August 2010
Phase: N/A
Study type: Interventional

The majority of teeth utilized in the fabrication of conventional complete dentures are made of acrylic resins. These acrylic teeth provide increased bond strength to the denture base and are much easier to adjust for correct denture occlusion compared to teeth made of harder materials, such as porcelain. However, the acrylic teeth will wear faster than the porcelain teeth, leading to alterations in how the teeth contact each other if the denture is not replaced periodically (typically every 5-8 years). With the increase in biting and chewing forces that can be achieved during function with dentures supported by dental implants, the rate of tooth wear may be increased, leading to more frequent need for replacement of the prosthesis. Acrylic teeth made of nano hybrid composite material (NHC) potentially offer greater wear resistance and aesthetic characteristics. The NHC teeth employ a wide range of fillers, including highly cross-linked organic macrofillers, high-density inorganic microfillers and silanized silica based nanofillers. The macrofillers are, to a large part, responsible for the adequate strength and color-stability of the teeth, whereas the microfillers improve the wear resistance. The nanofillers offer fundamentally different optical behaviour from those of larger fillers, improving light reflection without lowering the translucency. This offers additional opportunities in the development of composite teeth, which have to exhibit lifelike aesthetics and translucency. These teeth made of nano-particles and hybrid composites can be made with two different techniques, one where the materials are pressed together and another using an injection technique. The injection method has been found to have better aesthetic results, but resistance to wear in clinical use has not been established. The purpose of this study is to evaluate the wear characteristics of new resin denture teeth (nano particles - hybrid composite) made by an injection technique. Twenty-four edentulous subjects will be enrolled who have completed implant placement for mandibular implant overdentures opposing a maxillary complete denture or implant overdenture, or patients that have previously received these dentures and are interested in having new dentures. Both maxillary and mandibular dentures will be fabricated using injection molded nano-hybrid composite denture teeth. The wear of denture teeth will be evaluated using stereophotographic recordings at baseline, 6, 12, 18 and 24 months after denture treatment.
