Objective: Assess the clinical effects, 3D radiographic results and patient-reported outcome measures (PROMs) of buccal bone regeneration combined with piezocision. Methods: Ten patients presenting roots prominence with a thin buccal bone thickness or buccal bone dehiscence in the lower front region were enrolled. Patients received orthodontic treatment assisted by piezocison which was combined with a buccal alveolar bone regeneration using a tunneling approach. A comparison between pre- and post-treatment alveolar bone measurements based on CBCT was performed. Periodontal parameters such as recession scores and root resorption were recorded before and after treatment. The PROMs were also investigated. Results: An overall significant buccal bone gain of 2.7 2.7% was found after the treatment. The apical region reached the highest gain of 8.9 5.5% whereas the most coronal region showed no significant increase of the bone envelope (1.2 2.7%). No adverse event such as the appearance of recession or root resorption were observed. However, in 2 patients, the biomaterial was not properly integrated and seemed to be encapsulated. The pain level and the paracetamol consumption were equivalent to those after the placement of the orthodontic appliance except on the day of the surgery. Conclusions: Within the limitation of this study, piezocision combined with buccal bone regeneration using a tunneling technique seems to be effective to augment bone and did not lead to gingival recession. However, in 2 cases the biomaterial seemed encapsulated, and therefore the predictability of the integration of the material can be questioned. [less ▲]

Objectives: Implants with a triangular neck were recently introduced to limit peri-implant bone loss. The primary objective of this randomized controlled trial was to compare peri-implant bone changes of circular versus triangular cross-section neck implants 1-year after loading. The secondary objectives were to assess buccal hard tissue thickness changes, Pink Esthetic Score (PES) and patient satisfaction. Material and methods: Thirty four patients requiring replacement of the single, intercalated missing tooth of healed site for at least 4 months in the posterior maxilla were randomized into 2 groups according to the type of implant. Immediately after surgery and 1 year after final restoration, a cone beam CT (CBCT) was performed to assess proximal bone remodeling and buccal bone thickness. Peri-implant soft tissue health, PES and patient-reported outcome measures (PROMs) were recorded. Results: No implant loss occurred within the follow-up period. The mean ± SD peri-implant proximal bone loss 1-year after loading was 0.22 ± 0.30 mm for triangular and 0.42 ± 0.67 mm for circular implants necks (p=0.25). Peri-implant bone loss exceeding 2 mm was observed in a single implant in the circular neck group. Buccal bone thickness remained stable and did not differ different between the 2 groups. The peri-implant soft tissue health, PES and patient satisfaction were also comparable. Conclusions: Within the limitations of the present study, patient clinical and radiographic outcomes did not differ between triangular and circular cross-section neck implants in the posterior maxilla.

Objective : To explore patient-related outcomes measures (PROMs) of piezocision-assisted orthodontic treatment compared to aconventional orthodontic treatment using customized appliance. Materials and methods : Twenty-four adult patients requiring orthodontic treatment for mild-to-moderate overcrowding in both jaws were randomly assigned to a test group, treated with a piezocision-assisted orthodontic treatment, or to a control group, where piezocision was not applied. The patient-related outcomes were recorded using a 0–10 visual analog scale (VAS). Daily analgesic consumption and pain level were also recorded following the placement of the orthodontic appliance in both groups and after the piezocision procedure in the test group. Moreover, levels of apprehension and satisfaction were also assessed in both groups. Results : In the piezocision group, over the 7-day period, paracetamol consumption was comparable after the placement of the orthodontic appliance and after the piezocision surgery. Pain levels after the orthodontic and the surgical procedure decreased with time (p < 0.0001) but remained globally higher after piezocision (p = 0.0056). Significantly, more patients of the piezocision group reported that they would undergo the treatment again (p = 0.033) and that they greatly appreciated the duration of treatment(p = 0.0008). However, the level of apprehension was significantly higher in the piezocision group compared to the test group(p =0.012). Conclusions : Although, the degree of apprehension before the surgery and higher pain level in the piezocision group, PROMs emphasized similar pain killer consumption in both group and revealed high acceptance and satisfaction with piezocision approach. Clinical relevance : The benefit of piezocision-assisted orthodontic treatment seems to be relevant from a patient perspective. Trial registration : NCT03406130 [less ▲]

Introduction: The duration of orthodontic treatment in adults remains a barrier for some patients. Some surgical techniques have been developed in order to accelerate orthodontic tooth movement. The technique of corticotomies is effective in decreasing the orthodontic treatment time but remains invasive, leading to significant postoperative consequences. Materials and Methods: Minimally invasive techniques without muco-periosteal flap elevation have been developed: corticision, micro-osteoperforations, piezopuncture and piezocision. Results: The piezocision procedure seems to be the best compromise to accelerate orthodontic tooth movement while respecting a specific surgical and orthodontic protocol. The piezocision surgery allows the addition of biomaterials in cases of dehiscence and/or fenestration on the alveolar bone associated with moderate to severe overcrowding. Conclusion: According to current publications, minimally invasive corticotomy techniques can be viewed as a new therapeutic tool in the acceleration of orthodontic tooth movement. [less ▲]

OBJECTIVE: The aim of this study was to investigate the effects of piezocision (surgical protocol with sutures) in orthodontic treatment using CAD/CAM (computer-aided design and computer-aided manufacturing) customized orthodontic appliances. DESIGN: The study is designed as a parallel group, randomized controlled trial (RCT). SETTING: University Hospital. ETHICAL APPROVAL: The study was approved by the ethic committee of the University Hospital Liege, Belgium. SUBJECTS AND METHODS: This RCT was conducted on 24 adult patients requiring orthodontic treatment to release mild overcrowding. Patients were all treated with a customized appliance and randomly assigned by means of sealed envelopes containing group codes to either a test group treated with piezocision or a control group without any further treatment. A blinded orthodontist validated appliance removal or further adjustments based on the model study. OUTCOME MEASURES: The overall treatment time and the time between archwire changes were recorded. Moreover, clinical and radiological features such as tooth resorption, gingival recessions, and the presence of scars were evaluated. RESULTS: A total of 24 patients (12 control and 12 test) completed the study. The overall treatment time was significantly shorter in the test group than the control group. Likewise, the time difference between all arch changes was significantly lower when piezocision was performed, except for the first arch at the mandible and the last arches at both maxillae. During the fine-tuning phase, no significant difference was found between the two groups. All periodontal and radiographic parameters remained stable from the start to the end of treatment in both the groups. However, minor scars were found in 66 per cent cases. LIMITATIONS: This trial was a single-centre trial. CONCLUSIONS: Piezocision seems to be an effective method to accelerate orthodontic treatment in cases of mild overcrowding. However, the effect was only observed during the alignment phase and a greater efficiency was found in the maxilla. The technique may be contraindicated in patients with a high smile line since the risk of slight scarring exists. REGISTRATION: ClinicalTrails.gov (Identifier: NCT03406130). [less ▲]

The primary objective of this pilot study was to evaluate a new socket preservation technique involving the intentional expansion of the extraction socket buccal plate using a flapless internal corticotomy and biomaterials. A total of 11 patients requiring tooth extraction were enrolled in this study. The aim of this technique was to maintain or improve the hard and soft tissue contour of the ridge after tooth extraction. All surgical sites healed uneventfully. Significant alveolar bone dimension changes were observed in the coronal region of the ridge (-1.4 ± 0.9 mm); however, it was only slightly lower at the medium (-0.35 ± 0.7 mm) and apical levels (-0.3 ± 0.8 mm) (P > .05). The ridge dimensional changes were significantly higher in the buccal aspect than in the palatal aspect in all patients. Vertical bone resorption was not significant. Concerning the soft tissue contour, the horizontal distance between the preoperative and postoperative buccal profiles ranged from 0.94 to -2.88 mm. The proposed ridge preservation technique may help maintain the volume of the healed ridge but cannot completely prevent contour changes after tooth extraction. [less ▲]

Abstract Aims: The objective of this study was to assess prospectively the outcomes of extra-narrow diameter implants (XNDI) placed in teenage patients as a temporary restorative option. Material and Methods: Twenty consecutive young patients presenting one or several missing teeth received XNDI that were immediately restored with composite, Polymethylmethacrylate (Acrylic) or ceramic crown. Clinical and radiographical outcomes were assessed for a minimum follow-up period of 1 year. Additionally, each patient completed retrospectively a satisfaction questionnaire using Visual Analog Scale (VAS). Results: A total of 30 implants were placed and followed for a period of 1–7.4 years (mean: 3.59 years). One implant failed after 3 weeks and was replaced successfully. No further biological complications occurred during the follow-up period, leading to an implant survival rate of 96.6%. The patient satisfaction evaluations displayed high levels of comfort and function. Conclusion: Immediately restored XNDI to replace missing teeth on teenager patients seems to be an effective temporary restorative option to replace missing teeth in young patients. Composite or ceramic crowns should be preferred. Clinical trials with long-term follow-ups and the assessment of passive egression are needed. [less ▲]
