Outcome of combined orthodontic-surgical treatment in a United Kingdom university dental institute

Abstract

This investigation demonstrates that in terms of static occlusion combined orthodontic-orthognathic surgery is effective in correcting severe malocclusion.

Occlusal outcomes in combined orthodontic and orthognathic treatment

“…For this reason, it should also be expected that orthognathic patients show a greater reduction in number and percentage of PAR points. The mean pre-treatment PAR score was comparable to the mean PAR score at the start of treatment in other orthognathic studies, for example, 37.6 (Baker et al, 1999), 38 (Ponduri et al, 2011) 39.09 (Cartwright et al, 2016) and 40.48 (O'Brien et al, 2009). In comparison, the pre-treatment mean PAR score in patients undergoing orthodontic treatment has been shown to range from 28.7 (Birkeland et al, 1997) and 29.8 (Baker et al, 1999).…”

“…They concluded that orthodontic/orthognathic treatment was effective in correcting dental and skeletal discrepancies. More recently, further retrospective evidence has shown that combined treatment is effective in correcting severe malocclusion (Cartwright et al 2016).…”

Orthognathic Surgery Treatment Need in a Turkish Adult Population: A Retrospective Study

“…IOFTN is a newly developed index, and a limited number of studies have been published on IOFTN so far [14,15,16,17,18,19]. Harrington et al [19] conducted a retrospective study using the data of Northampton General Hospital in the UK and reported that the most prevalent IOFTN score was 5.2 (increased overjet > 9 mm), followed by 5.3 (reverse overjet ≥ 3 mm), and 4.2 (increased overjet ≥ 6 mm and ≤ 9 mm).…”

“…Similar to other occlusal indices, there are some limitations using IOFTN. It does not assess the sagittal, vertical, and transverse skeletal relationships, which can be compensated by the teeth [14,17,26,27]. Another limitation is that there is no score in the IOFTN that only represents the chin deformity.…”

“…This was mainly to correct the maxillary transverse deficiency prior to orthognathic surgery. Reviewing previous studies it is not clear if they included cases with distraction osteogenesis as a part of dentofacial deformity correction [14,18,32].…”
