Background : In the process of placing an oseointegrated implant into the resorbed maxillary posterior region, there is often a need for sinus floor elevation. Usually the maxillary sinus pneumatizes toward the ridge crest after dental extraction. Thus, there is a consequent decrease in the available bone height, disfavoring prognosis and preventing implant placement. Aims or Objectives : The objective of the present study was to evaluate and compare two different techniques for sinus floor elevation along with setting oseointegrated implants.
Methods : Twelve patients, 35-45 years old, ten males and two females underwent implant rehabilitation in the maxillary premolar/molar region. Half of the patients were managed by the modified Summers’ osteotome technique , and the remainder by the SINUS UP technique.
Results : Each technique showed advantages and disadvantages.
Conclusions : 1.The osteotome technique was found to be suitable for elevating the antral membrane when an average increase of 3 to 4 mm bone was needed, and at least 4 mm remaining. Its high success rate shows an image of long term bone formation. 2.Where ridge resorption is more advanced and at least 4 mm is remaining, a lateral antrostomy is required in order to end up with sufficient bone height for adequate implant length. 3.The different sinus elevation techniques did not seem to affect the implant success rate. Using β-TCP in the strip form opens up new possibilities for sinus lift procedures, since it simplifies this surgical technique.

Objectives: The objective of this study was to evaluate the effectiveness of a nonsurgical treatment regimen in the long-term control of necrotic areas of the jaws and pain in such patients.
Methods: A total of 96 patients suffering from the disease were included in this study. All patients received nonsurgical treatment regimen for 10 days, and repeated every 3 months for 2 years. The size of the osteonecrotic lesions was measured and the pain level was self-assessed with a visual analog scale.
Results: The patients showed a statistically significant (F = 16.1; p < .01; r2 = .95) gradual decrease in the size of exposed bone areas during the nonsurgical therapy (from 12.5 to 8.8 mm). Pain scores ranged from 0 to 3 score scale. Complete resolution of the disease was observed in some patients.
Conclusions: This conservative nonsurgical treatment regimen seems to provide successful treatment in reduction of the sizes of exposed bone areas in the majority of patients.

ABSTRACT :
There is a paucity of recent data regarding osteomyelitis of the jaws (OMJ) particularly in Saudi population . Patients with inflammation of the jaw attended King Abdulaziz University Hospital , Faculty of dentistry oral surgery clinics and many medical centers in , Jeddah , KSA from Jan. 1990 - Dec. 2010 underwent retrospective chart review with regard of OMJ to assess the encountered risk factors . Forty-two patients , out of one thousand charted in such period , met the criteria for OMJ (37 definite, 5 probable). Mean age was 58 years. Most common risk factors associated with OMJ were tooth extraction, orofacial malignancy and radiotherapy. Most common symptoms were pain, exposed bone/plate and cheek swelling. Aerobic (GP 84%, GN 42%) and anaerobic (GP 53%, GN 27%) bacteria were identified. Thirty four % of patients received > 4 weeks of IV antibiotics. Five patients achieved full recovery. Limited recovery was associated with orofacial malignancy and radiotherapy ( p = 0.06 ). Radiotherapy for orofacial malignancy has emerged as major risk factor associated with OMJ. Only orofacial malignancy and radiotherapy predicted limited recovery. Length of antibiotic therapy or hyperbaric oxygen therapy (HBOT) did not predict treatment outcome.

ABSTRACT :
The incidence of localized osteitis after extraction in patients under oral contraceptive Pills was studied . Three common types used by Egyptian women ; namely Ovulen , Ovral , and Microvlar were evaluated and the incidence of localized osteitis after extraction was considered . The overall incidence of localized osteitis in these patients was found to be 22.85 % . However , it is 2.85 % in normal women . It was found also that great incidence of localized osteitis occurred in women taking ovulen tablets ( 31.42 % ) , followed by ovral ( 22.85 % ) and microvlar ( 14.28 % ) , respectively . Finally , it was concluded that Microvlar is a reasonable drug in eliciting localized osteitis in Egyptian women using oral contraceptive Pills .

ABSTRACT :
A new technique for closure of chronic oro-antral fistula is described . In this technique , the fistulous tract is everted towards the oral cavity through the opening of the fistula . Then , instead it is incised and removed as usual , it is sutured with the surrounding mucoperiostium. It is a relatively simple procedure , neither a graft nor an alloplastic material or others is needed . This technique proved effective in closing all cases .

A new lesion of concern with startling clinical appearance . It is characterized mainly by punched out , sharply demarcated , craterous ulcer . The ulcer is almost covered with necrotic tissue and is not painful , bearing a very strong resemblance to squamous cell carcinoma . Histologically , the lesion mimic also carcinoma . However , the lesion is benign and self-healing . Healing is generally slow , requiring up to 8 weeks for complete resolution .

ABSTRACT :
Patients with chronic TMJ disorders associated with disc displacement without perforation were collected . Preoperative MRI findings , pathologic findings , and surgical findings were correlated to each other . MRI was found to be a reliable noninvasive procedure that clearly demonstrates TMJ structures . It is effective in revealing disc displacement .

ABSTRACT :
Numerous bone grafting techniques with and without immediate implant placement have been advocated . A maxillary one stage antral and nasal lift techniques combined with free autogenous corticocancellous iliac bone grafts secured by endosseous titanium implants were performed to nine patients suffering from compromised maxilla , with great survival and success rates .

ABSTRACT :
Bone grafting of the cleft maxilla and palate has caused considerable controversy and discussion .Too often clefts of the palate treated by conventional methods lead to collapse of the lesser segment of the maxilla and limit the potential of orthodontic treatment .Effects of early bone grafting on facial skeletal growth in patients with cleft lip and palate . It was shown that there were no unwarranted growth restrains compared with a similar series having no clefts .It was clear that early maxillary orthodontia and primary osteoplasty , done with care and in a planned sequence with lip and palate closure , has several advantages .
