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.
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.

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.
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.
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).
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.
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.
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.
