Introduction: Osseodensification is a non-extraction technique using specially designed drills to increase bone density while extending an osteotomy, allowing bone to be preserved and condensed by compacting autograft during osteotomy preparation, increasing bone density around implants, and improving mechanical stability. Aim: The objective of this study is to compare conventional osteotomy and osseodensification protocols in implant placement and analyze whether there are differences in bone density. Materials and Methods: Study variables were defined, namely, osseodensification technique, conventional osteotomy technique, bone density, sex, area of location, implant dimensions, implant dimensions, and implant stability. Eligibility and exclusion criteria were defined. A step-by-step surgical protocol was developed. The surgeon and radiologist underwent intra-examiner calibration. A total of 15 patients were selected according to the eligibility criteria, and a total of 41 implants were inserted, 20 implants by conventional osteotomy and 21 by osseodensification. A cone beam computed tomography was performed one year after prosthetic rehabilitation to estimate bone density. Data were collected and recorded, and in the analysis of the association of variables, non-parametric tests were applied. Results: Significant statistical results were found in bone density values, with higher values being obtained with the osseodensification technique, that is, median density values of 1020, and median density values of 732 for the bone drilling technique. The results of the correlation between bone density in both techniques and sex, primary implant stability, implant dimensions and location area were statistically non-significant. Conclusions: Within the limitations of this study, there are differences in bone density between conventional osteotomy and osseodensification protocols. Bone density is increased with osseodensification over a study period of one year.

<strong data-sider-select-id="db762fef-c999-47e9-9451-cf1efb55563a">Background. Modifying the dental implant’s surface texture enhances its biological response to the bone and implant‒tissue interface, resulting in the successful support of forces. This study assessed the impact of sandblasting, sandblasting plus acid etching, Er,Cr:YSGG laser, and propolis implant surface treatments and occlusal load on the osseointegration of titanium dental implants in dogs. <strong data-sider-select-id="491b6d14-e639-433f-9f28-4c5f7549e85a">Methods. Seventy-two titanium dental implants with a diameter of 4 mm and a length of 10 mm were divided into four groups according to implant surface modifications (n=18 for each group): group A: sandblasting plus acid etching, group B: sandblasting with Al2 O3 , group C: Er,Cr:YSGG laser, group D: propolis coating. Twenty-four local breed male dogs were used. Premolar teeth (P1, P2, and P3) were extracted on the left side of the mandible, and after 12 weeks of bone healing, implants were unilaterally installed. The osseointegration at three study times from implant installation (14, 90, and 180 days) was evaluated. The dog jaws were scanned using an intraoral scanner for the virtual design of screw-retained three-unit crowns after 90 days of osseointegration. Final radiographs were taken before the animals were sacrificed at 14, 90, and 180 days, and the histological analysis was performed. <strong data-sider-select-id="58f5e1a3-d137-4c81-aaf5-58b34e3196c0">Results. Radiographic analysis showed new bone formation (NBF) along and in contact with the implant surface of the treated groups. The histological analysis after 14 days in groups A and B revealed a uniform and ongoing pattern of bone growth and many osteoblasts with few osteocytes within lacunae in new bone trabeculae. Group C showed an increase in the number of osteoblasts lining thin bone trabeculae. Group D showed a generative power concerning bone. At 90 days, there was increased bone ingrowth, and the new bone matured in all the treated implant groups. At 180 days, dense mature bone apposition was in direct contact with delayed-loaded implant surfaces. <strong data-sider-select-id="fec6857b-61c7-41fd-8786-2318861f18f2">Conclusion. A radiographic examination revealed that surface modification significantly impacted osseointegration, with a strong bond between the implant surface and the surrounding bone. The histological sections at the 14-day interval revealed obvious bone remodeling activity, especially in sandblasting plus acid etching and sandblasting-modified implant surface groups. At the 90-day interval, bone ingrowth had increased, and the new bone became mature, especially in sandblasting and propolis surface modification groups. After 180 days of the delayed-loaded implant osseointegration, differences were observed between different implant-treated groups with a remarkable remodeling of the bone, especially in the propolis coating group.

“…The implant site should remain undisturbed for a minimum of 3–8 months to promote proper healing and osseointegration between the implant and bone. 1 Titanium and titanium-based alloys have been widely used as dental implants because of their mechanical properties and bioinert. It has been pointed out to have problems such as Young's modulus being significantly higher than that of bones 2 and being extremely difficult to machine.…”
