ABSTRACT
Alveolar cleft reconstruction is a major challenge in cleft lip and/or palate [CLP] patients and golden standard protocol is to perform bone grafting [BG] before canine eruption and subsequent orthodontic closure. Objective of this study was to compare the post operative morbidity of two procedures in terms of complications i.e. the average operation time, intra-operative blood loss, postoperative pain and to demonstrate the surgical procedure and clinical outcome in terms of preservation of the grafted alveoli. This was a prospective comparative study conducted at the Department of Oral and Maxillofacial Surgery, Children Hospital, Lahore on twenty patients with residual alveolar clefts. The patients were randomly divided into two groups A and B. In group A, the cancellous bone graft was harvested from the anterior iliac crest while in group B, the cancellous bone was harvested from the anterior iliac crest and mixed with Synthetic bone substitutes in 1:1 by volume. The patients in group B recovered from walking uncomfortably statistically faster than those in group A. The duration of the hospital stay was significantly shorter in group B than in group A. The average bone graft densities of both groups significantly reduced within 6 months after grafting then seemed to be stable until month 24. The bone graft heights gradually decreased with time, in both groups by 24 months postoperatively. It was concluded that efficacy of hydroxylapatite is comparable with that of autogenous bone alone in terms of bone remodeling and tooth eruption, either spontaneous or orthodontically assisted
ABSTRACT
The purpose of this study was to identify the cephalometric skeletal morphological features of anterior open-bite [AOB] in adult Pakistanis. It was a cross sectional descriptive study having quantitative study design. Lateral cephalograms of 30 pre treatment anterior open-bite patients with the age range 17 to 27 years, coming to the department of Orthodontics were taken [18 females and 12 males]. Subjects of study sample were clinically diagnosed as having open bite.In addition the subjects were considered as having skeletal AOB when SN-GoGn angle was equal to or more than 32.5 degree. Ten linear and angular measurements were recorded. The results showed significantly increased values of linear measurements [PHF, AFH, UFH] and angular measurement[SN-GoGn].One angular measurement[SN-PP] was closer to the mean Caucasian sample values but there was more obliquity to the Gonial angle. The ratio PFH/AFH was small as compared to white anterior AOB subjects. Sexually dimorphic variables were also identified by independent sample t-test
