“…For instance, it has been reported to effectively manage cases with a gummy smile to produce overbite and decrease underlying extensive gingival display. 39,40 Previous comparative investigations also demonstrated that adding TADs to the conventional approaches is usually with reduced adverse events by minimizing the risk of tooth movement. 41,42…”

Treating various types of malocclusion is dependant on providing a secure anchorage. In this context, it has been shown that teeth, intramaxillary, and/or extraoral appliances are required to achieve favorable outcomes regarding anchorage treatment. A Temporary anchorage device (TAD) has been introduced in the literature in this context. It has been described as a temporary device that can be used after completing treatment. The aim of the study was to review the indications and uses of TADs in orthodontic treatment. The current evidence shows that introducing TADs in the field of orthodontic treatment has been associated with favorable outcomes that encountered the previous multiple challenges reported with the conventional anchorage approaches. Contemporary orthodontic settings reported various uses for TADs, including corrections in transverse, vertical, and anteroposterior dimensions. Combined use of TADs and conventional approaches were also evaluated with favorable outcomes. These findings indicate the validity of TADs in orthodontic treatment and call for its future implications and clinical applications. However, it should be noted that post-treatment evaluation on a long-term basis was not adequately reported in the current literature, indicating the need for future investigations for further validation.

“…Four different models were created with the above general descriptions and the following specifics ( Figure 1 ). Two of them were inspired by two case reports [ 4 , 12 ], but the other two were designed by the authors. In all models, the length of miniscrews were based on earlier references [ 4 , 12 , 13 ].…”

“…In the past, dentoalveolar extrusion and increased maxillary height could only be corrected through orthognathic surgery, which is an invasive procedure [ 3 ]. However, with the advent of temporary skeletal anchorage devices (TADs), it has been reported that in some cases, gummy smiles caused by dentoalveolar extrusion and increased maxillary height can be corrected [ 3 , 4 ]. Some case reports have shown that a miniscrew can achieve the same effect as maxillary impaction with Le Fort I surgery, and this way a gummy smile can be corrected with the full intrusion of the maxillary arch [ 5 ].…”

Introduction. Absolute anchorages obtained from temporary anchorage devices (TADs, miniscrews) considerably facilitate dental movements and make some very difficult movements such as full-arch intrusions possible. Despite the significance of assessing strategies to fully intrude the arch using mini-implants, there is no study in this regard except a few case reports. Therefore, we simulated/tested 4 scenarios. Methods. Four maxilla models were created with different miniscrews/appliances: (1) two miniscrews were placed distal to laterals and one in the mid sagittal region. (2) Two mini-implants were inserted in mesial of canines and 2 others between bilateral first and second molars, plus another TAD in the midpalatal area, plus a transpalatal arch (TPA). (3) Two mini-implants were inserted between bilateral canines and first premolars and 2 others between bilateral first and second molars + TPA. (4) Two mini-implants were installed between lateral-and-canine and 2 miniscrews between second premolars and first molars + TPA. Intrusive forces (80 g anterior, 150 g posterior) were exerted using stainless-steel coil springs. Stresses/displacements were measured. Risk of external root resorption was evaluated. Results. The highest amounts of incisor/molar intrusion were seen in model 1. Model 2 had fewer intrusions, but its control over undesired movements was greater. Model 4 drastically reduced molar intrusion and considerably increased premolar intrusion. Overall amounts of intrusion were highest in the first 2 models, marking them as proper candidates for cases needing greater intrusion extents. Model 2 may be useful when miniscrew loosening/failure is a concern, while model 1 is recommended when fewer miniscrews are allowed. Overall, the highest and lowest root resorptions might occur in models 1 and 4, respectively. Conclusions. Each model showed certain efficacies/drawbacks and thus is recommended for a particular set of cases. Therefore, depending on the diagnosis and treatment plan, one or more of these scenarios might be desirable.

“…It is agreed worldwide that excess of more than 3 mm is considered to be unattractive (2)(3)(4) . Many modalities have been advocated to restore the dentogingival relation for the management of gummy smile those of which includes; crown lengthening procedures (5) , orthodontic leveling of the gingival margins of maxillary teeth (6) , intrusion of the upper teeth (7) , orthognathic surgery (8) , botulinum toxin injections (9) and lip repositioning surgery (10) .…”

Objective: The present study was performed to evaluate the success rate of the lip repositioning surgery by assessment of the soft tissue changes and the relapse associated with that procedure. Methods: six female patients were included in the study who suffered from gummy smile ranging from 4-6 mm due to hypermobility of the upper lip or short upper lip. Pre-operative measurement of the amount of gingival display during smiling was recorded digitally using Adobe Photoshop cs6 through well standardized photographs. Lip repositioning surgery was performed under local anesthesia for all patients by removing a strap of epithelium through an elliptical outline followed by primary closure of the wound by interrupted 0-5 resorbable suture. All patients were followed up at 14 days, 4 months, 8 months and 12 months, postoperative assessment was done by measuring the same preoperative measurement. Results: Post-operative measurements at 14 days follow up, showed marked reduction in the gingival display. However complete relapse was observed at 4smonth and thereafter. Conclusion: Lip repositioning surgery isn't an effective technique in addressing excess gingival display with almost complete relapse associated with the procedure.
