Evaluation of the levels of pain and discomfort of piezocision-assisted flapless corticotomy when treating severely crowded lower anterior teeth: a single-center, randomized controlled clinical trial.

ABSTRACT: BACKGROUND:No randomized controlled trial (RCT) has compared flapless piezocision-assisted corticotomy in the extraction-based orthodontic decrowding of lower anterior teeth with the conventional treatment in terms of pain, discomfort and acceptability. Therefore, the aim of this trial was to compare piezocision-based orthodontic decrowding of lower anterior teeth following premolar-extraction with the conventional orthodontic treatment regarding levels of pain, discomfort, and patients' satisfaction. METHODS:A parallel-group RCT was conducted on 34 patients with severely crowded lower anterior teeth. Subjects were randomly allocated to either the experimental (ExpG) or the control group. Piezoelectric corticotomies were performed on the labial surfaces of the alveolar bone in the anterior region in the ExpG. Levels of pain, discomfort, swelling, difficulties of mastication, swallowing and jaws movement limitation were recorded on a Visual Analog Scale (VAS) at 1, 7, 14 and 28?days. In the ExpG, patients were also asked to rate their level of satisfaction following acceleration. Two-sample t tests were employed to detect significant differences. RESULTS:No statistically significant differences were found between the two groups at one day following treatment commencement regarding pain, discomfort, difficulties of mastication, swallowing and limitation in jaws movement (P?=?0.082, 0.367, 0.062, 0.446, 0.359; respectively). However, a statistically significant difference was found between the two groups regarding the perception of swelling at the first-day assessment (P?=?0.011). No statistically significant differences were detected between the two groups at 7?days regarding the five previously mentioned variables. There was a drop down to zero level at two weeks and four weeks following treatment onset for all variables. The level of satisfaction in the ExpG had a mean value of 86.47 (±22.47) and all patients were positive towards recommending the surgical intervention to a friend. CONCLUSIONS:No significant differences in the levels of pain and discomfort were found between the ExpG and the control group for all variables except for the perception of swelling at one day following intervention. Patient-centered outcomes revealed a high level of acceptance and satisfaction with this technique. TRIAL REGISTRATION:This trial was registered at Clinical Trials.gov (Identifier NCT02975765 ).

Project description:BACKGROUND:To evaluate the effectiveness of two minimally invasive surgical procedures in the acceleration of canine retraction: piezocision and laser-assisted flapless corticotomy (LAFC). METHODS:Trial design: A single-centre randomized controlled trial with a compound design (two-arm parallel-group design and a split-mouth design for each arm). PARTICIPANTS:36 Class II division I patients (12 males, 24 females; age range: 15 to 27 years) requiring first upper premolars extraction followed by canine retraction. INTERVENTIONS:piezocision group (PG; n?=?18) and laser-assisted flapless corticotomy group (LG; n?=?18). A split-mouth design was applied for each group where the flapless surgical intervention was randomly allocated to one side and the other side served as a control side. OUTCOMES:the rate of canine retraction (primary outcome), anchorage loss and canine rotation, which were assessed at 1, 2, 3 and 4 months following the onset of canine retraction. Also the duration of canine retraction was recorded. Random sequence: Computer-generated random numbers. Allocation concealment: sequentially numbered, opaque, sealed envelopes. Blinding: Single blinded (outcomes' assessor). RESULTS:Seventeen patients in each group were enrolled in the statistical analysis. The rate of canine retraction was significantly greater in the experimental side than in the control side in both groups by two-fold in the first month and 1.5-fold in the second month (p?<?0.001). Also the overall canine retraction duration was significantly reduced in the experimental side as compared with control side in both groups about 25% (p???0.001). There were no significant differences between the experimental and the control sides regarding loss of anchorage and upper canine rotation in both groups (p?>?0.05). There were no significant differences between the two flapless techniques regarding the studied variables during all evaluation times (p?>?0.05). CONCLUSIONS:Piezocision and laser-assisted flapless corticotomy appeared to be effective treatment methods for accelerating canine retraction without any significant untoward effect on anchorage or canine rotation during rapid retraction.

Project description:Background and objectivesBoth invasive and minimally invasive surgical methods have recently gained popularity in accelerating orthodontic tooth movement. Traditional corticotomy (TC) was one of the first effective invasive surgical techniques in shortening orthodontic treatment time, whereas the flapless cortico-alveolar perforations (FCAPs) technique is a modern minimally invasive method that has recently shown good results in different types of orthodontic tooth movement. Therefore, this study aimed to compare the effectiveness of TC versus FCAPs in maxillary canine retraction when treating Class II division 1 malocclusion patients.Materials and methodsThis was a single-blinded, single-center, three-arm randomized controlled trial. A total of 51 patients (22 males, 29 females, mean age 20.98 ± 1.95) whose treatment planning included the extraction of maxillary first premolars were enrolled and randomly divided into three groups: the TC group, the FCAPs group, and the control group. The assessed outcomes were the amount of canine retraction, anchorage loss, and canines' rotation, which was evaluated at five-time points till the completion of canine retraction.ResultsThere were statistically significant differences in the amount of canine retraction between the three groups in the first two months (p < 0.001), with greater mean values in the TC group (p < 0.001) in the first month. However, the amount of canine retraction in the FCAPs group was significantly greater in the second month compared to the TC group (p = 0.003) and the control group (p < 0.001). In the first month of canine retraction, anchorage loss, and canine rotation were significantly lesser in the TC and FCAPs groups than in the control group (p < 0.001). On the contrary, the canines' rotation amount after the completion of retraction was greater in the TC group than in the other two groups (p < 0.001).ConclusionTC and FCAPs are efficient adjunctive surgical methods for accelerating canine retraction. At the end of the first month, the TC accelerated canine retraction by 59.85% and FCAPs by 44% compared to the conventional retraction. At the end of the second month, the acceleration was less than recorded in the first month (35.44% and 50.20%, respectively). The acceleration effect of the surgical interventions appeared transient and did not last in the following observation period.
