Brief Summary
in the last years, dentistry is going to the concept of conservatism to preserve the most amount of tooth structure, so the evolution of new ceramic materials with invasive designs like (inlay- shaped and proximal box shaped) inlay retained bridge, the investigators can restore single missing posterior teeth with less invasive techniques and less rate of restoration fracture.

Outcome Measures
Primary Outcomes (1)
fracture
resistance of restoration to disintegrate and the assessment for the outcome will be done by using MUSPHS scale and the measuring unit is score
1 year
Study Arms (2)
( proximal box design)
EXPERIMENTALThe proximal box at least ( 1mm wide and has 6◦ divergences, and extend 2 mm apical to the isthmus floor.
( inlay shaped design)
ACTIVE COMPARATORThe occlusal inlay has a preparation depth of 2.0 mm for the ceramic. The occlusal preparation ( 4 mm wide and extend 4mm for premolar and 6 mm for molar mesiodistally
Interventions
inlay retained bridge is the less invasive type to restore single missing teeth in the posterior area
Eligibility Criteria
You may qualify if:
- Absence of periapical or periodontal or diseases
- sound abutment teeth or with small caries or filling on occlusal or proximal surfaces
- Maintenance of good oral hygiene
- No tooth mobility or grade 1 can be accepted
- Sufficient occluso-gingival tooth height (5mm)
- Good alignment of abutment teeth
- mesiodistal edentulous space preferred not exceed 12mm
You may not qualify if:
- Patients under the age of 18 or being incapable of taking out a contract
- Patients with any medical condition that impaired correct oral hygiene
- Endodontic ally treated abutment teeth
- a conspicuous medical or psychological history
- bruxism, or known allergic reaction to the materials used
- limited vertical space for the required connector height of 4mm
- pregnant female patients
