4 Years Clinical and Radiological Evaluation of Dental Implant Placed in Regenerated Bone vs Dental Implant Placed Into Native Bone

Objectives: BONE REGENERATIVE PROCEDURES ARE STILL A CHALLANGE FOR THE SURGEON. THE CLINICIANS HAVE TO EVALUATE SEVERAL PAREMETER BEFORE PLACING DENTAL IMPLANT IN ORDER TO HAVE A PREDICTABLE CLINCIAL LONG TERM SUCCESS. VERTICAL AND HORIZONTAL JAW BONE DEFECT CAN BE TREATED WITH SEVERAL BONE AUGMENTATION TECHNIQUE AND IT SEEMS TO HAVE EXCELLENT RESULTS A THE TIME OF THE SURGERY BUT SOME LIMITATIONS AT THE LONG TERM CLINICAL CONTROL.
AIM OF THIS STUDY IS TO EVALUATE BY USING CLINICAL AND RADIOGRAFIC INSTRUMENTS THE BONE LOSS AND THE SOFT TISSUE HEALING IN THE NATIVE BONE VS REGENERATED BONE.
Methods: 28 PATIENTS THAT NEED SINGLE TOOTH RESTORATION BY PLACING DENTAL IMPLAT-SINGLE CROWN HAVE BEEN EVALUATED IN THE STUDY. ALL THE PATIENTS SATISFIED INCLUSION CRITERIA ACCORDINGLY WITH GOOD GENERAL HEALTH CONDITION. 16 PATIENTS SHOWED HORIZONTAL DEFECT AND NEED BONE REGENERATIVE PROCEDURE BEFORE DENTAL IMPLANTS POSITIONING IN ORDER TO HAVE ADEQUATE HARD AND SOFT TISSUE VOLUMES. THE BONE REGENERATIVE PROCEDURE INVOLVED DEPROTEINIZED BOVINE BONE PARTICLES AND COLLAGENE MEMBRANE ACCORDINGLY WITH THE EXCELLENT RESULT OF THE RECENT LITERATURE.
Results: NO IMPLANTS WERE LOST AT THE 4 YEARS FOLLOW UP CONTROL. THE CONTROL VISITS WERE FIXED AT 6-12-24-36-48 POST OP BY USING CLINICAL (PERIODONTAL EVALUATION BLEEDING INDEX) AND RX EVALUATION. THE 12 PATIENTS UNDERWENT DENTAL IMPLANT PLACEMENT WITHOUT REGENERATIVE PROCEDURE (GROUP A) SHOWED EXCELLENT CLINICAL RESULTS. THE 16 PATIENTS THAT PRESENTED BONE DEFECT BEFORE THE SURGERY (GROUP B) SHOWED RESULTS NOT SIGNIFICANTLY DIFFERENT FROM THE GROUP A
Conclusions: THE PRESENT STUDY WANTS TO HIGHLIGHTS HOW SIMPLY REGENERATIVE PROCEDURE FOR MANAGING HORIZONTAL DEFECTS AND CONSEQUENT DENTAL IMPLANT SURGERY CAN BE CONSIDERED A PREDICTABLE TECHNIQUE AND COMPARABLE WITH THE STANDARD SURGERY ON NATIVE BONE.
