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.

Detailed Description

It has been demonstrated that a great amount of tooth structure is lost during the prosthetic preparations of abutments for full-coverage FDPs with tooth substance removal of 63% of 73%, this aggressive loss of tooth structure usually accompanied with pain and postoperative sensitivity. In comparison With the inlay-retained bridge, there is less amount of tooth substance loss. this clinical study will provide benefits for practitioners and clinicians by guiding them to choose a more conservative treatment plan with the better marginal fit, clinical performance and satisfaction for the patients on the long term. rather than other benefits like less chair time, less risk for pulp injury, less time and cost

Conditions

Study Groups

( proximal box design)

The proximal box at least ( 1mm wide and has 6◦ divergences, and extend 2 mm apical to the isthmus floor.

Group Type: EXPERIMENTAL

proximal box inlay retained bridge

Intervention Type: OTHER

inlay retained bridge is the less invasive type to restore single missing teeth in the posterior area

( inlay shaped design)

The 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

Group Type: ACTIVE_COMPARATOR

proximal box inlay retained bridge

Intervention Type: OTHER

inlay retained bridge is the less invasive type to restore single missing teeth in the posterior area

Interventions
