The present clinical study was undertaken to determine the effects of splinting overunsplinted mobile teeth following periodontal surgery and compared the efficacy of two splinting materials, i.e. Ribbond ribbon + Composite with Stainless steel wire + Composite. Materials and methods Total of 30 patients (20 experimental and 10 control) formed the study group. Entire study was extended over a period of 12 weeks for each patient and treatment plan was divided into 8 phases. Healing response was monitored and application, durability, biocompatibility of splint material was assessed. Results Splint had a promising and beneficial effects on anterior teeth exhibiting Grade I to Grade II degrees of mobility. Experimental group showed a greater reduction in tooth mobility compared to control group. There was no significant difference in plaque index and Ribbond Ribbon reinforced with composite resin was an excellent material for application, patient comfort, resistance to fracture, biocompatable and esthetic acceptability. Clinical significance Splinting is recommended as an adjunct to periodontal surgery in the treatment of hypermobile teeth, especially in cases where patient discomfort is a prominent factor.

Objective: To compare and evaluate the fracture toughness and flexural strength of PMMA and bisacryl composite provisional restorative materials with and without reinforcement of Kevlar fibre. Methodology: 40 test specimens of PMMA and bisacryl composite for fracture toughness testing and 40 rectangular specimens of PMMA and bisacryl composite for flexural strength testing were fabricated respectively. Each main group was again divided into 2 sub groups A & B; where A is control group and B is the test group with Kevlar fibre reinforcement. The fibre reinforced specimens were prepared by precutting the fibres into 12mm and 23mm length and wetted using the polymer monomer mix for the PMMA and a bonding agent for the bisacryl resin and then placed in the mold cavity. In both tests, unreinforced resins were used as control group. Specimens were stored in water at 37˚C for 24 hours before testing. The specimens were loaded in universal testing machine. The mean fracture toughness and mean flexural strength were compared by one way analysis of variance followed by the Tukeys standardized range test. Results: The mean fracture toughness and flexural strength values obtained were significantly higher for bisacryl composite when compared to PMMA. Similarly after Kevlar reinforcement bisacryl composite proved to be better.
