Muscle Activity Evaluation of Maxillary Bilateral Bounded Partial Denture Fabricated By Bre-Flex Versus Peek

Study Overview
=================
Brief Summary
-----------------
Evaluation of the muscle activity of masseter in tooth borne partial denture wearers (class III modification 1 Kennedy's classification) with two different denture base materials (Breflex and PEEK) by means of electromyograph.

Official Title
-----------------
Muscle Activity Evaluation of Maxillary Bilateral Bounded Partial Denture Fabricated By Bre-Flex Versus Peek (Randomized Clinical Trial)

Conditions
-----------------
Maxillary Class III Modification I Edentulous Patients

Intervention / Treatment

Participation Criteria
=================
Eligibility Criteria
-----------------
Inclusion Criteria: All patients must have Kennedy class III modification I upper partially edentulous ridges. The remaining teeth have good periodontal condition, with no signs of attrition or gingival recession. All patients have skeletal Angle's class I maxillo-mandibular relationship and have sufficient interarch distance. Free from any systemic or neuromuscular disorder that might affect chewing efficiency of masticatory muscles. Free from any tempro-mandibular joint disorder. The patients have good oral hygiene and low caries index. Exclusion Criteria: Patients having abnormal habits as bruxism or clenching. Patients having hormonal disorders as diabetes, thyroid or parathyroid hormonal diseases were not included. Teeth with compromised bone support. Patient with xerostomia or excessive salivation. Patient with abnormal tongue behavior and/or size.
