Study type | Interventional |
When missing tooth structure or teeth are replaced, minimal biologic risk should be involved
to re-establish function and esthetics. The increased use of the adhesive technique and
preservation of dental tissues have greatly impacted conservative tooth preparation design.
The development use of zirconia technology and all-ceramic systems has opened the potential
for fabrication inlays zirconia bridges with durability and good aesthetics.
The purpose of this study is to clinically evaluate the placement of inlay bridge made of a
Y-TZP framework veneered with a pressed ceramic and bonded with a completely adhesive
approach in the replacement of a single missing tooth.

Inclusion Criteria: 1. Good oral hygiene 2. Low susceptibility to caries 3. Parallel alignment of abutment teeth 4. Immobility of the abutment teeth 5. Minimum height of abutment teeth = 5 mm (connector thickness) 6.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Other | Change in Sensitivity | The presence of any spontaneous or stimulated pain will be assumed. | Immediately within five minutes following cementation (T1), 3 months (T2), 6 months (T3), 12 months (T4) following application | |
Other | Change in Patients' Satisfaction | A questionnaire will be used to detect the level of satisfaction regarding function and shade | Immediately within five minutes following cementation (T1), 3 months (T2), 6 months (T3), 12 months (T4) following application | |
Other | Change in Shade | The shade is going to be determined using Vita(R) shade guide. | Immediately within five minutes following cementation (T1), 3 months (T2), 6 months (T3), 12 months (T4) following application | |
Primary | Change in marginal fit | To examine if there is a gap between inlay margins and tooth cavity margins .It will be measured by a probe. | Immediately within five minutes following cementation (T1), 3 months (T2), 6 months (T3), 12 months (T4) following application | |
Primary | Change in Material Integrity | To examine macroscopically the presence of cracks or fractures in the veneering ceramic (retainers or pontics) or any fractures at the connectors. | Immediately within five minutes following cementation (T1), 3 months (T2), 6 months (T3), 12 months (T4) following application | |
Primary | Change in the Retention Status | The resistance of a prosthesis to displacement will be measured. | Immediately within five minutes following cementation (T1), 3 months (T2), 6 months (T3), 12 months (T4) following application | |
Secondary | Change in Marginal Color Matching | Examination will be done macroscopically to detect the presence of any difference in color between the margins of the tooth and inlays | Immediately within five minutes following cementation (T1), 3 months (T2), 6 months (T3), 12 months (T4) following application |
