Brief Summary:
The present study will be performed to evaluate the effect of two implant placement systems conventional method and osseodensification method radiographically on bone density and bone height surrounding the implant by using CBCT and clinically by probing depth and gingival index
Detailed Description:
Atrophic maxilla or mandible can lead to lack of prosthesis retention because of an inadequate bearing area causing both functional and physiological problems for patient these problems can be treated for patient satisfaction with an implant supported fixed or removable complete or partial denture 1
The use of implants to retain a mandibular over denture has been recommended as the first treatment choice for the edentulous mandible From the available evidence it shows that this treatment leads to a great improvement in both clinical function and patients reported outcomes when compared to conventional complete dentures 2
Clinical studies have reported that dental implants in the mandible have higher survival rates compared to those in the maxilla having thinner cortical bone combined with thicker trabecular bone compared to the mandible 3 In contrast to the previous studies additional studies in the posterior mandible showed high failure rates due to the poor bone quality as well as other additional factors 3-4
The osseointegration process leads to new bone apposition on the implant surface and allows reaching the implant secondary stability that is the functional contact between living bone and titanium dental implant 4
Primary implant stability is affected by both the quality and the quantity of bone of the osteotomy site Hence a precise evaluation of bone structure is essential before implant placement implant 5 The term bone quality depends on bone density bone vascularity bone metabolism and other factors that may affect implant outcome Many authors describe bone density as being equivalent to bone quality This includes physiological and structural parts and the degree of bone tissue mineralization 4-5
2 Successful dental implant placement requires sufficient amount of bone thickness covering the implant so that primary stability is achieved which is an important requirement for long term success of the implant 2 6
Primary implant stability is defined as the biomechanical stability upon implant insertion being influenced by numerous factors such as bone quantity and quality the geometric design of the implant surgical technique and insertion torque From this stability new bone develops around the surface of the implant constituting a biological fixation named secondary implant stability 7 8
The longevity of any implant prosthesis depends on successful osseointegration and implant stability Consistent osteotomies and densification are important to implant primary stability and to early loading 9 10
Unlike traditional bone drilling technologies osseodensification does not excavate bone tissue Rather it preserves bone bulk so bone tissue is simultaneously compacted and autografted in an outwardly expanding direction to form the osteotomy 11 12 It creates a densified layer of surrounding bone through compaction autografting while simultaneously plastically expanding the bony ridge at the same time 13 1415
The new burs allow bone preservation and condensation through compaction autografting during osteotomy preparation increasing the peri-implant bone density BV and the implant mechanical stability 16
Osseous densification was shown to increase the insertion and removal torques of the implants compared to standard drilling and extraction drilling This demonstrates increased implant primary biomechanical stability 17
3 Osseodensification had a direct impact on increasing the values of peak insertion torques of the implants compared to cutting drilling which indicates enhancement of initial stability of implant fixture 18
