“…Another important factor affecting osseointegration is hydrophilicity/hydrophobicity. Thus, hydrophilic materials with a surface tension higher than 30 dyne/cm interact more closely with biological fluids, cells, and tissues and, consequently, contribute to a better osseointegration process [350,377]. The roughness of the implant surface also plays a certain role in this process.…”

The development of dental implantology is based on the detailed study of the interaction of implants with the surrounding tissues and methods of osteogenesis stimulation around implants, which has been confirmed by the increasing number of scientific publications presenting the results of studies related to both the influence of the chemical composition of dental implant material as well as the method of its surface modification on the key operational characteristics of implants. The main materials for dental implant manufacturing are Ti and its alloys, stainless steels, Zr alloys (including ceramics based on ZrO2), and Ta and its alloys, as well as other materials (ceramics based on Al2O3, Si3N4, etc.). The review presents alloy systems recommended for use in clinical practice and describes their physical–mechanical and biochemical properties. However, when getting into the body, the implants are subjected to various kinds of mechanical influences, which are aggravated by the action of an aggressive biological environment (electrolyte with a lot of Cl− and H+); it can lead to the loss of osteointegration and to the appearance of the symptoms of the general intoxication of the organism because of the metal ions released from the implant surface into the biological tissues of the organism. Since the osteointegration and biocompatibility of implants depend primarily on the properties of their surface layer (it is the implant surface that makes contact with the tissues of the body), the surface modification of dental implants plays an important role, and all methods of surface modification can be divided into mechanical, physical, chemical, and biochemical methods (according to the main effect on the surface). This review discusses several techniques for modifying dental implant surfaces and provides evidence for their usefulness.

“…The roughness of the implant surface also plays a certain role in this process. Fibroblasts and epithelial cells adhere more strongly to smooth surfaces, and the ability to ensure osteoblast proliferation and collagen synthesis is more pronounced on a surface with moderate roughness [377].…”

Introduction. Dental implantation is getting more popular with patients who require total dental rehabilitation. Patients note that possibility of immediate loading based on dental implants is more favorable treatment option due to active social life. Low bone density, often occurred in the maxilla, frequently presents challenges for clinicians to achieve successful implant primary stability for predictable immediate loading.The aim of our study was to increase the efficiency of treatment of patients who require dental implantation in the maxilla.Materials and methods. Twenty-seven patients aged from 27 to 66 years with missing teeth in the alveolar process of maxilla were treated. All patients in this randomized clinical trial were divided into two groups. We used two methods for implant site preparation: the standard technique according to manufacturer’s recommendations in the first group (n = 13) and the Osseodensification technique via Densah drills (n = 14) in the second. All patients were treated by Astra Tech dental implants with the same dimensions (diameter 4 mm, length 9 mm). Immediately after implant placement the data of the frequency-resonance analysis of the implant stability and insertion torque were installed and obtained. Furthermore, a comparison of the operation time was carried out. Clinical evaluation and patient appreciation of pain, edema and hyperemia of the mucosa were evaluated using a questionnaire at 1, 3, 5 and 7 days after surgery. The measurement of the values of the stability quotient of the implants was repeated and carried out after six months.Results. Higher values of implant primary stability (insertion torque and implant stability quotient during surgery) were showed in the osseodensification group (IT — (45,0±5,8), ISQ — (71,8±2,9)) in comparison with standard technique (IT — (27,7±3,8), ISQ — (62,8±3,2)); p < 0,05.Discussion. Osseodensification technique promotes compaction of a low density bone in direct contact with the implant, which leads to higher implant primary stability due to the physical interaction between bone and implant.Conclusion. The obtained results allow us to consider that the osseodensification method is progressive for improving the effectiveness of implantological treatment on maxilla.
