Preoperative removal of lower third molars and bilateral sagittal split osteotomy in the UK.

To find out what consultants in Oral and Maxillofacial Surgery (OMFS) in the UK think about complications of bilateral sagittal split osteotomy (BSSO) in relation to lower third molars we organised a national postal questionnaire during 2012-13. Of 378 consultants, 192 practised orthognathic surgery of whom 132 replied (a 69% response rate). Eighty-one respondents routinely removed lower third molars before BSSO; 51 did not.

Localization of ectopic maxillary canines -- is CBCT more accurate than conventional horizontal or vertical parallax?

Objective: To compare the accuracy of cone-beam CT (CBCT) with conventional horizontal and vertical parallax for the localization of ectopic maxillary canines.

Design: Observational study.

Methods: A typodont was constructed using human teeth embedded in radio-dense impression material, containing a simulated ectopic canine.

The characteristics of bisphosphonate patients developing bisphosphonate-related osteonecrosis of the jaw attending an OMFS department.

Unlabelled: This case series considers the incidence of patients taking bisphosphonate medication that suffer with bisphosphonate-related osteonecrosis of the jaw (BRONJ) following an exodontia procedure. Forty five such patients who attended the Wigan Royal Albert Edward Infirmary (RAEI) Oral and Maxillofacial Surgery (OMFS) department for an exodontia procedure were examined. A patient's age, gender, exodontia technique, bisphosphonate route (Oral/IV), smoking status and reason for taking the bisphosphonates, eg osteoporosis/cancer/ arthritis was considered.

Mandibular advancement appliances for treating sleep apnoea/hypopnoea syndrome.

Study Design: Randomised controlled crossover trial.

Intervention: Sixteen participants (13 men and three women) with mild to moderate OSAHS, diagnosed using polysomnography (PSG), were recruited from a sleep clinic. To be included, participants had to have 20 or more teeth (sufficient to provide retention for oral appliances), have had no previous OSAHS treatment, been unable to tolerate nasal continuous positive airway pressure and be free from caries, periodontal disease, temporomandibular joint (TMJ) pain or movement limitations.
