“…Additionally, Trisi et al 5 have shown that OD allows the use of wider implants diameters in narrow edentulous ridges, with consequent increase in bone volume. This increase in bone was later shown to reach 30% of the original ridge dimensions by Podaropoulos 6 .…”

“…Osseodensification (OD) burs, working in a non-subtractive fashion, condense the implant osteotomy soft bone in lateral direction, leading to a greater bone volume and density, an increase in the bone implant contact, with subsequent increase in insertion torque levels, and reduction in micromotion 2– 6 . However, it has been claimed that OD increases the implant bone bed density, but does not improve implant primary stability 7 .…”

Background: It is difficult to achieve good primary stability of dental implants in soft bone, such as that in the posterior maxillae. Osseodensification (OD) burs, working in a non-subtractive fashion, condense the implant osteotomy bone in lateral direction and increase in the bone implant contact. Also, dental implants with deeper threads, and decreased thread pitch can increase initial bone implant anchorage. Methods: This study utilized 48 custom-made machined surface dental implants that were 13 mm long, with a major diameter of 4.5 mm and a minor diameter of 3.5 mm, a thread pitch of 1 mm, a thread depth of 0.5 mm, and a 4 mm long cutting flute at the apex. The implants were divided into 4 groups, each group was made of 12 implants with a different thread design; V-shaped, trapezoid, buttress, and reverse buttress. The implants were inserted in 4-mm thick cancellous bone slices obtained from the head of Cow femur bone. The ostoetomies were prepared by conventional drilling and by OD drilling. Each inserted implant was then tested for primary stability using the Periotest. The Periotest values (PTVs) for the implant stability were tabulated and analyzed using a chi square test at significance level p< 0.05. Results: The results of this this study revealed no statistically significant difference between the Periotest readings for the implants in each category placed in either the OD or the regular osteotomies. However, it has been found that the implants placed in regular drilling ostoetomies had a significantly better primary stability than the implants placed in OD osteotomies. Conclusions: It was concluded that OD is not necessary in situations where there is bone of good quality and quantity.

“…In this paper, we analyzed the osseodensification technique operating in the opposite rotatory direction than the conventional drills due to the use of different drills with an exclusive and patented design. Because of this technique, it is possible the bone condensing toward the osteotomy walls within the same surgery moment of the implant site preparation [ 9 , 10 , 11 , 12 , 13 , 14 , 15 ].…”

Many different osteotomy procedures has been proposed in the literature for dental implant site preparation. The osseodensification is a drilling technique that has been proposed to improve the local bone quality and implant stability in poor density alveolar ridges. This technique determines an expansion of the implant site by increasing the density of the adjacent bone. The aim of the present investigation was to evaluate the effectiveness of the osseodensification technique for implant site preparation through a literature review and meta-analysis. The database electronic research was performed on PubMed (Medline) database for the screening of the scientific papers. A total of 16 articles have been identified suitable for the review and qualitative analysis—11 clinical studies (eight on animals, three on human subjects), four literature reviews, and one case report. The meta-analysis was performed to compare the bone-to-implant contact % (BIC), bone area fraction occupied % (BAFO), and insertion torque of clockwise and counter-clockwise osseodensification procedure in animal studies. The included articles reported a significant increase in the insertion torque of the implants positioned through the osseodensification protocol compared to the conventional drilling technique. Advantages of this new technique are important above all when the patient has a strong missing and/or low quantity of bone tissue. The data collected until the drafting of this paper detect an improvement when the osseodensification has been adopted if compared to the conventional technique. A significant difference in BIC and insertion torque between the clockwise and counter-clockwise osseodensification procedure was reported, with no difference in BAFO measurements between the two approaches. The effectiveness of the present study demonstrated that the osseodensification drilling protocol is a useful technique to obtain increased implant insertion torque and bone to implant contact (BIC) in vivo. Further randomized clinical studies are required to confirm these pieces of evidence in human studies.

“…15 Additionally, it was shown that the use of Densah bur allows the insertion of wider implants diameters in narrow edentulous ridges, with consequent increase in bone volume to reach 30% of the original ridge dimensions . 16 Thus the Densah bur has the advantages of expanders combined with the high speed of standard drills and their tactile control. The drilling process using Densah burs can be either clockwise (CW) or counterclockwise (CCW) and is performed at high speeds 800-1500 rpm.…”

Aim: This study aimed to evaluate implant primary stability using Densah bur in comparison with expanders in maxillary premolar area. Material and methods:This study was conducted on twenty patients. The patients were divided into two equal groups. Each patient received one implant at the edentulous site of missing first or second maxillary premolar. One group received implants after using Densah bur, while the other group received implants after using screw expander. After implant placement, Smart peg was placed on implant and Ostell was used to record ISQ. Implant stability was measured intraoperative and at weeks 2, 4, 6, and 8 for both groups. The collected results were tabulated and statistically analyzed. Results:The study results showed there was no statistically significant difference between (Expander) and (Densah bur) groups in ISQ reading except at surgery and week two where the highest mean value was found in (Expander) group, while the least mean value was found in (Densah bur) group. Conclusion:Within the limitation of this study, Densah bur enabled successful implant insertion with acceptable primary stability in the resorbed maxillary premolar area. Moreover, the Densah bur can be used in a faster manner.
