This systematic review was conducted to evaluate the available literature on the clinical outcomes of the use of autogenous tooth bone graft prepared chairside, and its current applications. A literat...
The aim of the present study was to evaluate the relationship between soft tissues aesthetics and incisor torque, as well as the effect of crowding, anchorage, and extraction pattern, in adult patient...
Seventy-seven subjects with permanent dentition were selected retrospectively. Among these, 24 patients were treated with four extractions, 24 with two extractions and 29 without extractions. Lateral ...
The statistical analysis showed no differences within and between groups for soft tissue aesthetics. A significant reduction of the angle obtained from the intersection of Frankfurt plane and mandibul...
Similar soft tissue aesthetics were observed after treatment in the three groups, despite the presence of some skeletal and dental differences....
A well-controlled incisor torque helps to preserve soft tissues aesthetics. The type of anchorage could influence soft tissues....
The aim of this in vitro study was to evaluate the effect of a 3D-printed drill sleeve (DS) on the precision and duration of coronectomy sections....
Thirty-six trainees and oral surgeons performed 72 coronectomy cuts in a 3D-printed, entirely symmetric mandible model. Coronectomy was performed freehand (FH) on one side and with a DS on the other s...
In 7 cases, the sections were "too deep" with FH, while none with DS (OR: 18.56; 95%CI: 1.02-338.5; p = 0.048). The deviation between virtually planned and real cut depths was significantly greater in...
The DS effectively reduced tooth sectioning times by less experienced colleagues. Independently from the level of experience, the use of DS obviated the need for any preparation outside the lingual to...
Coronectomy sections may result in lingual hard and soft tissue injury with the possibility of damaging the lingual nerve. The precision of the buccolingual depth-control can be improved, while surgic...
Ridge resorption following tooth extraction may be reduced by alveolar ridge preservation (ARP). Previous randomized clinical trials and systematic reviews have suggested that autogenous tooth bone gr...
A systematic search was conducted in Cochrane Library, Embase, MEDLINE and Scopus for studies published from inception to 31 November 2021. We searched searched for randomized, non-randomized controll...
The analysis included eight studies for the primary and six for the secondary outcomes. The meta-analysis revealed a positive ridge preservation effect with a pooled mean difference ridge width change...
ATB is an effective particulate graft material in ARP. Complete demineralization of the ATB tends to decrease the proportion of newly formed bone. ATB can be an attractive option for ARP....
The study protocol was registered on PROSPERO (CRD42021287890)....
Primary canines and first molars can be extracted in a way that is associated with relatively low levels of pain and discomfort during and after the procedures. Double extractions induced more pain an...
Twenty-eight children, aged 9.5-14 years with displaced permanent maxillary canines were randomly assigned for extraction of the primary canine only or the primary canine and the primary first molar. ...
To assess pain, discomfort, and functional impairment in children experiencing extraction of primary canine or primary canine and primary first molar as an interceptive treatment for palatally displac...
Tooth extraction was associated with low levels of pain and discomfort on a group level. Extraction of both the canine and the first molar was associated with significantly more pain and discomfort th...
This study aimed to compare treatment efficacy and cephalometric outcomes between extraction and non-extraction MEAW therapies in non-growing open-bite patients....
22 Multiloop Edgewise Archwire MEAW patients (11 males, 11 females) and 15 bicuspid extraction patients (3 males, 12 females) were selected according to a strict inclusion criterion. Comprehensive dat...
The mean change in open bite closure was 3.07 ± 2.07 mm in the MEAW group and 3.03 ± 2.28 mm in the extraction group (P > 0.05). MEAW therapy was 31% faster (118 weeks) than extraction therapy (171 we...
In anterior open bite cases with bicuspid extraction, achieving a positive overbite typically involves retroclining and uprighting the upper and lower incisors (drawbridge effect). In contrast, the ME...
The MEAW appliance's biomechanical advantage in uprighting posterior teeth in open bite cases may shorten treatment duration for correcting open bite malocclusion....
To assess and compare the clinical, radiological, and histological outcomes of socket seal surgery between two protocols: deproteinized demineralized tooth matrix (dpDTM) and freeze-dried bone allogra...
Twenty extraction sockets in the anterior or premolar region were randomly allocated to either the dpDTM or FDBA protocol (n = 10 per group). Measurements of the alveolar ridge changes were obtained u...
Lower significant reductions in buccal alveolar ridge height and hard tissue volume were observed in dpDTM group compared to FDBA group at 3 months (0.25 ± 0.35 mm vs. 1.60 ± 0.66 mm [p = .000] and 9....
Alveolar ridge preservation using dpDTM is an efficacious procedure for providing the conditions for the development of functional and esthetic implants....
The periodontal status and distal bone level of the adjacent second molar can be negatively affected by the surgical extraction of an impacted lower third molar. Absorbable materials have some benefit...
Patients who met the inclusion criteria were randomized into three groups: secondary healing (n = 28), primary healing (n = 27) and membrane-based primary healing (n = 29). Digital panoramic radiograp...
Three of the applied healing types positively affected periodontal pocket depth (PPD) and periodontal index values (p < 0.05). In terms of the ABL of the adjacent 2Ms, primary healing (p < 0.05) and m...
Membrane use is promising for the distal bone gain and periodontal status of the adjacent 2M....
This clinical study was registered by the Australian New Zealand Clinical Trials Registry, with the trial number ACTRN12618001551280....
This chapter will discuss the orthodontic perspective of extractions of compromised first permanent molars (cFPMs) due to hypomineralisation. The context behind the diagnosis of a poor prognosis of cF...
