Brief Summary

evaluation of occlusal force distribution was carried out with the aid of T-Scan device (Tekscan Inc., South Boston, MA, USA) for mandibular complete dentures before and after relining with long term soft liner for controlled type 2 diabetic patients.

Outcome Measures

Primary Outcomes (1)

• assessment of the effect of relining of mandibular complete dentures with soft relining material on occlusal force distribution using T-Scan system. load distribution for 50 completely edentulous patient before and after complete denture relining

  Fifty completey edentulous patients having previously constructed and utilized conventional complete dentures were selected for this study. Relining of mandibular complete dentures with soft denture liner was carried out. Distribution of occlusal force was evaluated with the aid of T-Scan device before denture relining and three months after relining. measured before relining of complete denture with soft liner and measured again after complete denture relining.

  for each participant: the complete denture should be worn for three months

Study Arms (1)

changes in the occlusal load distribution

OTHER

A crossover clinical study was carried out with previously constructed and used conventional complete dentures before relining with soft denture liners and then with the same dentures after relining with soft denture liners. patients were comfortably using their relined mandibular complete dentures for at least three months and the retention and stability of the conventional dentures were assessed before second recording of occlusal parameter. The evaluation of occlusal force distribution was carried out with the aid of T-Scan device

Procedure: relining of mandibular complete denture

Interventions

relining of mandibular complete denture PROCEDURE

Relining of mandibular dentures was performed by reducing one mm of the denture fitting surfaces and borders to make a right-angled border. apply two separate layers of Mucopren adhesive upon the vestibular surface of the mandibular denture and allow each layer to dry for about 40 seconds. then, the lower denture was inserted and molded in patient mouths; while biting in centric occlusion with the opposing maxillary complete dentures.
