THE EFFECT OF LOW INTENSITY ULTRASOUND THERAPY ON OSSEOINTEGRATION OF TITANIUM DENTAL IMPLANT PLACED IN THE ESTHETIC ZONE

Background: Endosseous dental implants may be considered as the most popular treatment option for partially and fully edentulous patients. It is generally accepted that implant success is primarily dependent upon or achieved by osseointegration, a direct contact between the implant surfaces and living bone and gum. For decrease the time of osseointegration there is a different modalities used as altering the surface and/or shape of the implant has been frequently researched and it has been shown that rough implant surfaces allow a higher percentage of bone-to-implant contact compared to implants with smooth surfaces. Also dual acid etching of titanium, engineering of dental pulp cells on various implant surfaces and biomimetic implant coatings containing bone morphogenetic protein-2. Other methods studied to enhance endogenous bone healing around biomaterials are different forms of biophysical stimulations such as pulsed electromagnetic fields and low intensity pulsed ultrasounds (LIPU). Ultrasound is a form of energy that is transmitted through biological tissues as high-frequency acoustic waves, which is widely used in medicine as a diagnostic, therapeutic and operative tool.
The aim of the present study was to evaluate The effect of low-intensity pulsed ultrasound on the osseointegration of titanium dental implants .
Patient and methods: Ten implants were placed in ten patients each one receives one implant. The patients were 6 males and 4 females ranged in ages from 25 to 40 years. All the implants were placed in maxilla. Observations were made postoperatively at time of implant placement then after one month, 3 months, 6 months and one year follow up periods for crestal bone loss and stability, Data analysis was performed in several steps. Initially, descriptive statistics for each case results. One way ANOVA followed by pair-wise Tukey post-hoc tests were performed to detect significance between preparation cases. Statistical analysis was performed using Graph-Pad Prism-4 statistics software for Windows. P values ≤0.05 are considered to be statistically significant in all tests.
Conclusion: From the a aforementioned review it became clear that Low-intensity pulsed ultrasound could be accelerate the osteointegration of dental implant .
