“… 38 OD has also been indicated in the mandible as a favorable technique for alveolar ridge expansion. 23 , 39 Additionally, for implants placed in different‐density bone types in the anterior and posterior region of the maxilla, OD increased the bone density to such an extent that there was no significant difference between both areas in both IT values and ISQ values; while for SD, implants placed in the anterior region, predominantly D2 bone, presented higher IT values than in the posterior region, predominantly D3/D4 bone. Moreover, a similar remodeling rate was observed between both regions for both drilling techniques, with OD outperforming SD for all pairwise comparisons.…”

“…These anatomical areas are densely corticated and due to the sequellae of an inadequate downsizing osteotomy technique, necrosis and extensive remodeling may result 38 .

“…Given that removal torque was comparable throughout the healing period which was evaluated in this body of evidence, OD drilling has been suggested to provide atemporal biomechanical competence 17 . Clinical outcomes of OD technique have shown short‐ and long‐term efficacy in several clinical scenarios, thereby enhancing implant primary and secondary stability 22–24 . Therefore, this multicenter controlled clinical trial aimed to compare the IT values and temporal ISQ values (immediate, 3 and 6 weeks) of paired osteotomy sites prepared with standard SD and OD surgical instrumentation.…”

Background Osseodensification (OD) has shown to improve implant stability; however, the influences of implant design, dimensions, and surgical site characteristics are unknown. Purpose To compare the insertion torque (IT) and temporal implant stability quotients (ISQ) of implants placed via OD or subtractive drilling (SD). Materials and Methods This multicenter controlled clinical trial enrolled 56 patients, whom were in need of at least 2 implants (n = 150 implants). Patients were treated with narrow, regular, or wide implants and short, regular, or long implants in the anterior or posterior region of the maxilla or in the posterior region of the mandible. Osteotomies were performed following manufacturers recommendation. IT was recorded with a torque indicator. ISQ was recorded with resonance frequency analysis immediately after surgery, 3 and 6 weeks. Results Data complied as a function of osteotomy indicated significantly higher IT for OD relative to SD. OD outperformed conventional SD for all pairwise comparisons of arches (maxilla and mandible) and areas operated (anterior and posterior), diameters and lengths of the implants, except for short implants. Overall, ISQ data also demonstrated significantly higher values for OD compared to SD regardless of the healing period. Relative to immediate readings, ISQ values significantly decreased at 3 weeks, returning to immediate levels at 6 weeks; however, ISQ values strictly remained above 68 throughout healing time for OD. Data as a function of arch operated and osteotomy, area operated and osteotomy, implant dimensions and osteotomy, also exhibited higher ISQ values for OD relative to SD on pairwise comparisons, except for short implants. Conclusions OD demonstrated higher IT and temporal ISQ values relative to SD, irrespective of arch and area operated as well as implant design and dimension, with an exception for short implants. Future studies should focus on biomechanical parameters and bone level change evaluation after loading.

“…Hence, in the present case, GBR was performed before osteotomy expansion with osseodensification was done. 21 In the present case, prosthetic rehabilitation was done with the Toronto bridge technique or abutment-hybrid technique. 8,22 It was first described by Rajan and Gunaseelan for fabrication of retrievable combined cement-and screw-retained prosthesis for the single-tooth implant-supported prosthesis.…”

An implant-supported prosthesis offers a more predictable course of treatment as compared to other options available for rehabilitating edentulous arches and dental implants are a more acceptable treatment option to the dental fraternity and the public. Atrophic maxilla can be managed well utilizing autogenous bone grafts from intraoral donor sites, and the primary objective of this case was to use osseodensification as a means of acquiring more bone volume/density. We combined the use of three techniques, i.e., autogenous bone graft from symphysis, osseodensification drilling for implant placement, and Toronto prosthesis for rehabilitation of atrophic maxilla in a 35-year-old male patient. After 1 year of follow-up, the implant-based prosthesis is working well without any complication and established that autograft followed by osseodensification and rehabilitation with Toronto bridge gives good results. Block grafting followed by implant placement with osseodensification technique and Toronto prosthesis yielded great aesthetics and functional results.

Evaluation of instrumentation and pedicle screw design for posterior lumbar fixation: A pre‐clinical in vivo/ex vivo ovine model

Background Stabilization procedures of the lumbar spine are routinely performed for various conditions, such as spondylolisthesis and scoliosis. Spine surgery has become even more common, with the incidence rates increasing ~30% between 2004 and 2015. Various solutions to increase the success of lumbar stabilization procedures have been proposed, ranging from the device's geometrical configuration to bone quality enhancement via grafting and, recently, through modified drilling instrumentation. Conventional (manual) instrumentation renders the excavated bony fragments ineffective, whereas the “additive” osseodensification rotary drilling compacts the bone fragments into the osteotomy walls, creating nucleating sites for regeneration. Methods This study aimed to compare both manual versus rotary Osseodensification (OD) instrumentation as well as two different pedicle screw thread designs in a controlled split animal model in posterior lumbar stabilization to determine the feasibility and potential advantages of each variable with respect to mechanical stability and histomorphology. A total of 164 single thread (82 per thread configuration), pedicle screws (4.5 × 35 mm) were used for the study. Each animal received eight pedicles (four per thread design) screws, which were placed in the lumbar spine of 21 adult sheep. One side of the lumbar spine underwent rotary osseodensification instrumentation, while the contralateral underwent conventional, hand, instrumentation. The animals were euthanized after 6‐ and 24‐weeks of healing, and the vertebrae were removed for biomechanical and histomorphometric analyses. Pullout strength and histologic analysis were performed on all harvested samples. Results The rotary instrumentation yielded statistically (p = 0.026) greater pullout strength (1060.6 N ± 181) relative to hand instrumentation (769.3 N ± 181) at the 24‐week healing time point. Histomorphometric analysis exhibited significantly higher degrees of bone to implant contact for the rotary instrumentation only at the early healing time point (6 weeks), whereas bone area fraction occupancy was statistically higher for rotary instrumentation at both healing times. The levels of soft tissue infiltration were lower for pedicle screws placed in osteotomies prepared using OD instrumentation relative to hand instrumentation, independent of healing time. Conclusion The rotary instrumentation yielded enhanced mechanical and histologic results relative to the conventional hand instrumentation in this lumbar spine stabilization model.
