Impacted Third Molar Tooth, Swelling/ Edema

Keywords

piezosurgery, conventional osteotomy, impacted lower third molar, facial scan, 3d rendering

Brief summary

Aim of the study is to evaluate the swelling following the osteotomy when performed with drilling bur versus piezo-electric instrument in the mandibular impacted third molar extraction, using a facial reconstruction software

Interventions

PROCEDUREPiezo-electric surgery of impacted lower third molars

During lower third molar surgery, osteotomy is performed using piezoelectric instrumentation. When necessary, tooth sectioning was performed with a high-speed tungsten carbide slit drill under saline irrigation and the tooth removed in single or multiple segments.

PROCEDURERotary bur surgery of impacted lower third molars

During lower third molar surgery, osteotomy is performed using rotary instruments

Healthy volunteers

Inclusion criteria

* good general health conditions; * presence of bilateral and symmetrical impacted third molars (according to the classifications of Winter and Pell and Gregory);

Exclusion criteria

* no clinical evidence of major facial asymmetry; * use of medication that would influence or alter wound healing; * temporomandibular joint disorder history; * smoking

Design outcomes

Primary

Measure	Time frame	Description
Facial swelling	7 days	T0-T1 and T0-T2 scans are opened and superimposed through three reference points: endocanthion left (inner most point on commissure of left eye fissure), endocanthion right (inner most point on commissure of right eye fissure) and subnasale (mid point of columella). After matching, the swelling was calculated by selecting the area of the swelling and subtracting the two images.
