About this study

Official title: A Clinical Trial of Dental Device Made of Zirconia Cemented with PMMA Bone Cement on Partial Edentulous Patients of Kathmandu

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.

Read the 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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 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) Scan

    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.

    Measured: Total 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.

  2. Gingival status and health around dental device ("dantya nikhan") measured through Loe and Silness Gingival Index as Grade 0 to 3 and will be recorded with photographs

    During each visit of the participant every three months (four times in twelve months), or as requested by the participant, clinical examination including photographs will be conducted to evaluate soft tissue. Additionally Loe and Silness Gingival Index will be used to measure in grades 0 to 3, where Grade 0 means Normal gingiva (natural coral pink gingiva; no inflammation; no discoloration); Grade 1 means Mild Inflammation (slight change in color; slight edema; no bleeding upon probing); Grade 2 means Moderate inflammation (Redness; edema; glazing; bleeding upon probing); and Grade 3 means Severe inflammation (Marked redness and edema; swelling; possible ulceration; tendency to bleed spontaneously).

    Measured: Total 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.

  3. Oral Hygiene status around dental device ("dantya nikhan") measured through Quigley and Hein Plaque Index as Score 0 to 5

    During each visit of the participant every three months (four times in twelve months), or as requested by the participant, Quigley and Hein Plaque Index will be used to evaluate oral hygiene through Score 0 to 5, where Score 0 means No Plaque; Score 1 means Flecks of stain on the gingival margin; Score 2 means Definite line of plaque on the gingival margin; Score 3 means Plaque on gingival third of tooth surface; Score 4 means Plaque on almost two thirds of tooth surface; and Score 5 means Plaque on greater than two third of tooth surface.

    Measured: Total 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.

  4. Pain on and around dental device ("dantya nikhan") measured through Visual Analogue Scale as Score 0 to 10

    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.

    Measured: Total 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.

  5. Discomfort on and around dental device ("dantya nikhan") measured through Visual Analogue Scale as Score 0 to 10

    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.

    Measured: Total 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.

  6. Dislodgment of dental device ("dantya nikhan") measured through Present, Mobile and Absent

    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.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 14 Feb 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Nepal. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Parakram Parajuli, DMD (+9779851250250, parakramp@hotmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

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) Scan (time frame: Total 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.). The study lists 7 primary outcomes in all. It is what the study was designed to measure, not a finding.
