Summary

Commercially available implant surfaces are moderately roughened surfaces and they are obtained by acid-etching following alumina or titanium oxide grit-blasting. Although the micro-rough implants can be successful in compromised clinical scenarios, the bioinert nature of titanium surfaces cannot stimulate a more rapid bone regeneration and mechanical fixation of dental implants. Laser surface treatment is used to produce an implant surface modification on the nano-scale with controlled and reproducible patterns in addition to exhibiting a sterilizing effect and achieving efficient oxidation .

Detailed description

For dental implant to be successful, a direct contact between the bone tissue and the surface of the implant should be developed \& this physiological phenomenon is known by the term of osseointegration. Initially, it was supposed that to achieve osseointegration, implants had to be submerged under the mucosa \& left without any loading for a period of 3-4 months in mandible and 6-8 months in maxilla. Recently immediate implant placement at the time of extraction has become a viable treatment alternative, this approach provides the advantages of decreasing the patient's discomfort, the treatment's duration and costs. Aiming to reduce healing process to limit such changes in the soft \& hard tissues and reducing treatment time, several alterations in both surgical and restorative procedures has been introduced. From an implant design perspective, two approaches including the fields of biomaterials and/or biomechanics have been most utilized; implant body design which aim to increase the primary stability and surface modifications to allow faster osseointegration process. Rough implant surface is modified by different techniques. Among these different techniques, interest in of using laser to achieve roughened surfaces. Commercially available implant surfaces are moderately roughened surfaces and they are obtained by acid-etching following alumina or titanium oxide grit-blasting. Although the micro-rough implants can be successful in compromised clinical scenarios, the bioinert nature of titanium surfaces cannot stimulate a more rapid bone regeneration and mechanical fixation of dental implants.

Interventions

Type	Name	Description
DEVICE	laser and SLA	ligible patients will be randomized to 2 groups control group will receive SLA surface treated implant to replace badly broken tooth immediately after extraction and a study group will receive laser surface treated implant to replace badly broken tooth immediately after extraction. atraumatic extraction will be performed and socket will be examined for presence of bone dehesince or fenestration if no, implant will be placed immediately and a implant primary stability will be measured using an ISQ unit and recorded as base Line reading . gingival former will be attached to the implant and removed at 2 ,4,8,12 week intervals to record ISQ readings.
