Brief Summary

Conventional bridge and dental implants have been playing a significant role in replacing missing tooth/teeth. But they come with shortcomings. Hence, to explore the possibility of addressing such shortcomings, a clinical trial study of a new dental device made of zirconia is intended to be studied to see if it could serve as an additional option for fixed prosthodontics. An approach to explore possibilities for cheaper and faster procedure with regards to the treatment of tooth/teeth loss.

Detailed Description

Objectives:

To determine whether the use of a new dental device made of zirconia cemented with Polymethyl methacrylate (PMMA) bone cement could be an additional option for a faster treatment for missing tooth/teeth with fixed/removable prosthodontics.

Methodology:

After a Cone Beam Computed Tomography (CBCT) scan and clinical evaluation, 48 samples of zirconia dental device will be cemented with PMMA bone cement in edentulous area on randomized population. Immediate loading (0-15 days) with single crown and multiple unit bridge made of zirconia will be cemented using luting cement as fixed restoration. Radiographic evaluation and clinical examination will be conducted every three (3) months for one year.

Expected Outcome:

A new dental device made of zirconia could be an additional option for the treatment of edentulism, which could be completed within 0-15 days with minimal risk.

Primary Outcome Measures
NameTimeMethod
Dislodgment of dental device ("dantya nikhan") measured through Present, Mobile and AbsentTotal time frame is 16 months, 48 samples trial is to be completed in 4 months. Each sample will have follow up of 3 months for 12 months. The trial of samples on 4th month will complete the 12 months follow up in the 16th month.

During each visit of every three months (four times in twelve months), or as requested by the participant, dislodgment of dental device ("dantya nikhan") will be recorded through Present, Mobile and Absent, where Present means that the dental device has been completely detached from the osteotomy; Mobile means that the dental device is not completely detached, but is mobile; and Absent means that the dental device is neither completely detached from the osteotomy nor is mobile.

Pain on and around dental device ("dantya nikhan") measured through Visual Analogue Scale as Score 0 to 10Total time frame is 16 months, 48 samples trial is to be completed in 4 months. Each sample will have follow up of 3 months for 12 months. The trial of samples on 4th month will complete the 12 months follow up in the 16th month.

During each visit of the participant every three months (four times in twelve months), or as requested by the participant, pain on and around dental device ("dantya nikhan") will be recorded with Visual Analogue Scale through Score 0 to 10, where Score 0 means No Pain; Score 1-3 means Mild Pain; Score 4-5 means Moderate Pain; Score 6-7 means Severe Pain; Score 8-9 means Very Severe Pain; and Score 10 means Worst Pain.

Discomfort on and around dental device ("dantya nikhan") measured through Visual Analogue Scale as Score 0 to 10Total time frame is 16 months, 48 samples trial is to be completed in 4 months. Each sample will have follow up of 3 months for 12 months. The trial of samples on 4th month will complete the 12 months follow up in the 16th month.

During each visit of the participant every three months (four times in twelve months), or as requested by the participant, discomfort on and around dental device ("dantya nikhan") will be recorded with Visual Analogue Scale through Score 0 to 10, where Score 0 means No Discomfort; Score 1-3 means Mild Discomfort; Score 4-5 means Moderate Discomfort; Score 6-7 means Severe Discomfort; Score 8-9 means Very Severe Discomfort; and Score 10 means Worst Discomfort.

Marginal bone loss around dental device ("dantya nikhan") measured in millimeters (mm) through intra-oral x-ray and horizontal and vertical bone loss through Cone Beam Computed Tomography (CBCT) ScanTotal time frame is 16 months, 48 samples trial is to be completed in 4 months. Each sample will have follow up of 3 months for 12 months. The trial of samples on 4th month will complete the 12 months follow up in the 16th month.

During each visit of the participant every three (3) months (four times in twelve months), or as requested by the participant, intra-oral x-ray will be taken to evaluate hard tissue. Marginal bone loss, if any will be recorded in millimeters (mm). If additional issue (specially radiolucency) of hard tissue is detected then further evaluation through Cone Beam Computed Tomography (CBCT) Scan will be conducted.
