Dental implant A dental implant is biomedical device usually composed of an inert metal or metallic alloy that is placed on or within the osseous tissues. Dr. K.Jawad.H
Classification Of Dental implants Dr. K.Jawad.H
Osseointegration Bone formation that take place at the irregularities of the implanted material Dr. K.Jawad.H
Osseointegration depend on: 1- Biocompatibility of the implanted material. 2- Surface condition of the implant. 3- Design of the implant. 4- The surgical technique at insertion. 5- The loading condition applied afterward. 6- The status of the alveolar bone host bed. Dr. K.Jawad.H
The main differences between PD tissues around natural and implanted materials Dr. K.Jawad.H
Etiology of peri-implantitis 1- Bacterial infection (dental plaque). 2- Biomechanical factors. a- Excessive biomechanical forces. b- Loss of osseointegration. Dr. K.Jawad.H
Complications of untreated pei-implantitis Dr. K.Jawad.H
1- Infection. 2- Implant losing. 3- Bone destruction. 4- Gingival recession. 5- Implant fracture. Dr. K.Jawad.H
Treatment of peri implantitis Dr. K.Jawad.H
1- Initial phase of treatment A - Occlusal therapy: * Change in prosthesis design. * Improvement in implant number & position. * Occlusal adjustment. Dr. K.Jawad.H
B- Anti infective therapy: (Non surgical treatment) * Local removal of dental plaque. * Polishing. * Sub gingival irrigation with 0.12% chlorhexidine. * Systemic antimicrobial therapy. * Oral hygiene procedures. Dr. K.Jawad.H
2- Surgical phase of treatment: A - peri-implant resective therapy: Apically displaced flap technique that includes: * Correct horizontal bone loss. * Reduce pocket depth. * Surface polishing implantoplasty. Dr. K.Jawad.H
B - Peri-implant regenerative therapy: * guided tissue regenerative GTR. * bone graft technique. C - Removal of failed implants. Dr. K.Jawad.H
3 - Maintenance phase (follow up & recall) This include: Dr. K.Jawad.H
A - Examination and evaluation: * Status of the peri-implant soft tissue (gingiva) whether it is healthy or inflamed (GI). * Plaque &calculus accumulation (PLI). * Width of attached mucosa (gingiva). * Probing pocket depth. * Sulcus bleeding index (S.B.I) * Rate of sulcus fluid flow (GCF flow). Dr. K.Jawad.H
B - Instructions given to the patient to keep good oral hygiene: Home work therapy to control the dental plaque by using interdental brush ,single tuft brush ,dental floss, & super dental floss. Dr. K.Jawad.H
Thanks for your kind listening But lets see what was written in the next few slides Dr. K.Jawad.H
Why you should attend the lecture every week? Dr. K.Jawad.H
1 – There is a lot of useful information that you may miss if you don’t attend the lectures because these information can not be found neither in the dispensed written lectures nor the proposed text books . Dr. K.Jawad.H
2 – Your attendance will be appreciated as marks and credits that benefit you in the mid year and final oral exams. Dr. K.Jawad.H
3 – By your attendance you can participate in the short exams and quizzes that frequently carried out in each lecture . Like the ( opened book and help allowed quiz ) that will be appeared on the next slide. Dr. K.Jawad.H
How can you differentiate between hypoglycemic & hyperglycemic attacks on dental chair in a known diabetic patient ? Dr. K.Jawad.H
