Inclusion criteria

Inclusion criteria: Patients who need their maxillary or mandibular teeth to be restored and have the opposite teeth in functional occlusion and at least one proximal contact with the adjacent teeth Acceptable oral hygiene and periodontally healthy(plaque index and bleeding on probing had to be below 20% previously to the prosthodontic treatment) Good general health(no systemic disease that should negatively influence the clinical outcome) No obvious signs or symptoms of bruxing and/or clenching (bruxism such as attritions and existing fractures on the patients natural teeth or reconstructions, no pain on muscular palpation or tendomyopathies, No pain causing joint sound, no selfreported bruxing or clenching) The patient is ready to take part in the study and sign the testimonial

Exclusion criteria

Exclusion criteria: Presence of para-functional habits including clenching,bruxism or grinding Presence of periodontal problems and dental or medical history that can complicate the preparation of the restoration The lack of cooperation of the patients to observe oral hygiene( Plaque index and BOP should be below 20%)
