Effect of the Superhydrophilic Surface of Lance CLEAR Implants on the Marginal Bone Loss and Survival in Diabetic and Non Diabetic Patients

Diabetes Clinical Trial

Official title: A Comparative Prospective Study to Evaluate the Effect of the Superhydrophilic Surface of Lance CLEAR Implants on the Marginal Bone Loss and Survival in Diabetic and Non Diabetic Patients

Status Not yet recruiting

Clinical Trial Summary

The aim of this clinical, prospective study involving implants with a superhydrophilic surface is to compare the changes of the peri-implant tissues and the survival rate between diabetics and non-diabetics patients, after 12 months of loading.

hypothesis: It is not expected to find any short-term differences in failures and marginal bone loss between the diabetic and non-diabetic patients. On the longer term higher marginal bone loss may affect the diabetic group 40 patients who are planned to undergo implant installation will be enrolled in the study.

The patients will be divided into 2 groups:

• Test group - 20 patients diagnosed with type 2 diabetes with 10>HbA1C>7.5% values

• Control group - 20 non-diabetic patients.

Clinical Trial Description

In recent years, our understanding of the primary processes that affect bone growth around implants has progressed. It was found that the standard surface of most implants is not hydrophilic enough; therefore, it is necessary to increase the healing time to allow sufficient bony apposition at the implant interface, until reaching a satisfactory load-bearing capacity. Studies have demonstrated that surface superhydrophilicity can be gained following storage in an isotonic solution (NaCl); this feature leads to an earlier bone apposition and higher anchorage, already after the very first weeks of implantation.

Hypothesis: It is not expected to find any short-term differences in failures and marginal bone loss between the diabetic and non-diabetic patients. On the longer term higher marginal bone loss may affect the diabetic group.

Aim:to compare the changes of the peri-implant tissues and the survival rate between diabetics and non-diabetics patients, after 12 months of loading.

Methods and Materials: 40 patients who are planned to undergo implant installation will be enrolled in the study, at the department of Periodontology at the School of postgraduate dentistry in the Rambam Health Care Center. .

The patients will be divided into 2 groups:

• Test group - 20 patients diagnosed with type 2 diabetes with 10>HbA1C>7.5% values

• Control group - 20 non-diabetic patients. Visit 0 - Screening Visit 1 - Surgical procedure (± 8 weeks)

After insertion of the implants, the following surgical indicators will be taken:

1. Stability of the implants will be measured using an Osstell device with a fitted peg screwed into the implant neck; unit is given as an arbitrary implant stability quotient (ISQ).

2. Register bone quality type 1-4 according to the doctor report using Bone classification of Lekholm & Zarb ,1985.

Visit 2 - suture removal (10 ±3days) Visit 3 (surgical uncovering) 12 weeks after implantation (±8 weeks) Visit 4 (follow-up) 16 weeks after implantation (± 8 weeks) :this visit includes periodontal examination (PD, BOP, PI, GI) and GCF sampling.

Visit 5 ( Follow up ) 12 months after rehabilitation (± 4 weeks) :Clinical and radiographic assessment of the periimplant mucosa ;
