Material and Methods: The sample comprised 333 Libyan schoolchildren (162 males with a mean (SD) age of 14.4 (1.1) years, and 171 females with a mean age of 14.1 (1.1) years). Anterior and overall TSD ratios were computed using descriptive statistics. Sex differences were statistically assessed using an independent t-test (P<0.05). Results: Males showed significantly wider MD tooth width compared to females (P<0.05), except for the maxillary first premolars and mandibular central incisors. There were significant differences (P<0.05) between the paired (right and left sides) tooth measurements except for the maxillary and mandibular central and lateral incisors as well as mandibular canines.

This retrospective study assessed the orthognathic surgery procedures in two universities, using the Index of Orthognathic Functional Treatment Need (IOFTN), and compared the IOFTN grades according to gender as well as sagittal and vertical skeletal relationships. Material and Methods: Records of 200 consecutive patients (120 females, 80 males, mean age = 23.4 (SD: 5.4) years) who received orthognathic treatment (2014–2018) were analyzed.

Results: Class III, II, and I malocclusions formed 69%, 17.5%, and 13.5% of the samples, respectively. Class III skeletal relationships (69%) and high-angle cases (64%) were the most prevalent (p < 0.05).

This is usually performed after flap surgery, which is associated with moderate morbidity, as well as possible negative sequale such as gingival recession. The present case report illustrates the clinical benefits of vestibular incision subperiosteal tunnel access (VISTA) for SFOT, and tissue augmentation to facilitate orthodontic therapy. VISTA entails making vertical incision(s) in the vestibule followed by subperiosteal elevation of tunnels to provide direct access to the facial alveolar bone. Unlike previously reported vestibular access surgical procedures, VISTA allows for wider elevation of an access tunnel for clear visual and surgical access to perform careful inter-radicular corticotomy. The present report describes VISTA for corticotomy surgery (anterior mandible...

SBS and the adhesive remnant index (ARI) scores were recorded. Antibacterial activity against Streptococcus mutans in both groups after 24 h and 30 days was assessed (Disc agar diffusion test) and the inhibition zone diameter around each specimen was measured and recorded.

Vertical Alveolar Ridge Augmentation in Implant dentistry : A Surgical Manual, 2016
If implant placement is planned as a part comprehensive oral rehabilitation, appropriate root pos... more If implant placement is planned as a part comprehensive oral rehabilitation, appropriate root positioning by the orthodontist should be monitored with periodic radiographic assessments. Aiming for the ideal crown position, that is, crown torque and crown tip, can be misleading and would not necessarily lead to sufficient interradicular space and root parallelism suitable for implant placement. Therefore, orthodontic tooth movement should be guided by a three-dimensional need of the implant site dictated by the radiographical facts. A myriad of surgical techniques are available for reconstruction of the atrophic alveolar bone prior to implant placement. Some of the limitations of surgical reconstruction include lower efficiency of vertical augmentation, as well as the morbidity associated with augmentation procedures. Orthodontic therapy can be a useful adjunct for vertical down-growth of the alveolar crest and gingival margin, prior to implant placement. So far, the literature has offered limited information on comparison between the effectiveness of the surgical bone augmentation techniques and orthodontic alternatives and each method of implant site development has advantages and disadvantages. This chapter overviews orthodontic strategies that can aid in implant site development and maintenance. The following strategies will be briefly discussed: (1) orthodontic extrusion of compromised teeth, (2) tooth preservation and deferment of implant placement, (3) orthodontic implant site switching, and (4) the provision of a rigid bonded retainer to maintain the implant site.

This case report illustrates a novel approach of correcting mucosal recession around maxillary implants using guided bone regeneration (GBR) xenogenic resorbable membrane, and particulate allograft. A 22 year-old male patient presented with gingival recession and discoloration due to exposure of the 3 underlying dental implants in the maxillary esthetic zone 3 years after implant placement. Patient had bone loss confined to the labial surface of the implants, but no peri-mucositis/implantitis was present. A solvent-dehydrated mineralized allograft (Puros Cancellous Bone Allograft, Zimmer Biomet Dental, Palm Beach Gardens, FL) and a resorbable membrane (CopiOs Pericardium, Zimmer Biomet Dental) were used in a GBR surgical procedure in combination with placement of roughened titanium tenting screws 3-4 mm below the implant platfo...

Aiming for the ideal crown position, that is, crown torque and crown tip, can be misleading and would not necessarily lead to sufficient interradicular space and root parallelism suitable for implant placement. Therefore, orthodontic tooth movement should be guided by a three-dimensional need of the implant site dictated by the radiographical facts. A myriad of surgical techniques are available for reconstruction of the atrophic alveolar bone prior to implant placement. Some of the limitations of surgical reconstruction include lower efficiency of vertical augmentation, as well as the morbidity associated with augmentation procedures. Orthodontic therapy can be a useful adjunct for vertical down-growth of the alveolar crest and gingival margin, prior to implant placement. So far, the literature has offered limited information on comparison between the effectiveness of the surgical bone augmentation techniques and orthodontic alternatives and each method of implant site development has advantages and disadvantages. This chapter overviews orthodontic strategies that can aid in implant site development and maintenance. The following strategies will be briefly discussed: (1) orthodontic extrusion of compromised teeth, (2) tooth preservation and deferment of implant placement, (3) orthodontic implant site switching, and (4) the provision of a rigid bonded retainer to maintain the implant site.
