Evaluation of immediate loading of single dental implants in the maxillary esthetic zone: Clinical and radio graphical comparative study

In a prospective, comparative, clinical study 40 patients underwent single dental implant procedure in the maxillary esthetic zone. Twenty implants were placed into fresh extraction sockets (Group A), and the other 20 implants were placed into healed extraction sockets (Group B). All the procedures were carried out in the Department of Oral and Maxillofacial Surgery/College of Dentistry/Hawler Medi- cal University in Erbil, from March 2012 to March 2013.

Frequency of Dental Implants Placed in the Esthetic Zone in Dental Clinic of Tehran University: A Descriptive Study

Frequency of Dental Implants Placed in the Esthetic Zone in Dental Clinic of Tehran University: A Descriptive Study

Based on the current study results, of 2,381 implants placed in the maxillary esthetic zone, 23.0% had immediate, 0.7% had early and 76.1% had late placement. In the mandible, 8.3% had immediate, 0.2% had early and 91.5% had late placement. Some studies are in favor of immediate implant placement in the mandibular anterior region due to adequate primary stability and advantages of one-stage surgery as well as shorter duration of treatment. However, this is feasible only if the patient has perfect general health status and the mandibular bone is adequate for receiving four to six fixtures with a minimum length of 10mm and diameter of 3.75 to 4mm [10]. Based on our results, 32.1% of cases receiving implants in the maxillary esthetic zone and 14.3% of those receiving implants in the anterior mandible had bone grafts, which indicates that the bone deficiency could be more prevalent in the anterior maxilla than in the mandible. In this study, the failure rate of implants was 0.4% in the anterior maxilla and 0.9% in the

The dome technique: a new surgical technique to enhance soft-tissue margins and emergence profiles around implants placed in the esthetic zone

The dome technique: a new surgical technique to enhance soft-tissue margins and emergence profiles around implants placed in the esthetic zone

TI created this technique for cases where a tooth-bound single implant or two adjacent implants are placed in the esthetic zone, especially when it becomes apparent that the future crown facial margins and the soft-tissue zenith will be unfavorably more apical to the contralateral tooth and to the ideal and desired position. The name of the technique addresses the placement of the CT, as it is layered over the implant and takes the shape of an inverted dome.

Single piece implant placement with immediate loading in esthetic zone   case series

Single piece implant placement with immediate loading in esthetic zone case series

Immediate loading with immediate placement of implants involves placement of final restoration within 48 to 72 hrs . It is applicable only if sufficient primary stability is achieved. The technique was developed in response to patients with growing demand for quicker treatment and reduced time for the treatment. Among the several long term study performed with 5-10 year follow up, survival rate around 97% have been reported for immediate implants. The long term success and relative advantages of single piece immediate implant placement in the esthetic zone have been well documented,howeve this apprpach cannot be applied to every immediate implant patient.Careful patient screening and selection is the most important criteria along with adequate primary stability and proper occlusal table.

Modified Ridge Splitting and Bone Expansion Osteotomy with Guided Bone Regeneration by Demineralized Freeze-dried Bone allograft and Platelet-Rich Fibrin Membrane for Placement of Dental Implant in Esthetic Zone

Modified Ridge Splitting and Bone Expansion Osteotomy with Guided Bone Regeneration by Demineralized Freeze-dried Bone allograft and Platelet-Rich Fibrin Membrane for Placement of Dental Implant in Esthetic Zone

Modified ridge splitting and bone expansion osteotomy with guided bone regeneration by DFDBA and PRF membrane for placement of dental implant in esthetic zone showed the predictable results when proper case selection and careful surgery was performed. This technique if done skillfully and carefully can be helpful to expand and remove labial undercuts, which are major causes of fenestration during implant placement. This will also prevent off- axis loading.

<p>Influence of abutment material on the shade of dental implant restorations in the esthetic zone: a single case report</p>

Abstract: High esthetic demand and expectation challenges the rehabilitation of the esthetic zone with dental implants. Most implant system manufacturers offer customized and pre- fabricated ceramic, speci fi cally zirconia or alumina abutments, as an alternative to titanium or gold alloy abutments, with the aid of computer-aided designing/computer aided manu- facturing (CAD/CAM) technology. A 45-year-old male patient was referred to the prostho- dontics clinic for the restoration of maxillary central incisors with all ceramic dental implants. After healing, both implants were restored with all-ceramic crowns but different customized abutment materials for the purpose of comparison. The all-ceramic crown was cemented on a customized zirconia abutment at the implant site # 11 and on a customized gold alloy abutment at implant site # 21. The treating dentist as well as two prosthodontists performed a meticulous clinical examination to compare the ceramic crowns side by side and agreed that the outcome was esthetically satisfactory. The patient was satis fi ed with the esthetics and functional outcome of the fi nal restorations, as was the prosthodontist. Keywords: dental implant abutments, esthetic outcome, zirconia abutment

Treatment of labial soft tissue recession around dental implants in the esthetic zone using guided bone regeneration with mineralized allograft : a retrospective clinical case series

Treatment of labial soft tissue recession around dental implants in the esthetic zone using guided bone regeneration with mineralized allograft : a retrospective clinical case series

15 width of keratinize tissue, which has also been reported to help provide a peri-implant soft tissue seal against bacterial invasion, in addition to providing resistant against recession. 48 While increases in soft tissue thickness and keratinized tissue width have been reported after placement of connective tissue and free gingival grafts, 48 this phenomena has not been previously reported after GBR procedures around dental implants. The use of solvent-dehydrated, mineralized bone allograft and xenogenic pericardium membrane effectively increased alveolar hard and soft tissue dimensions in the esthetic zone of the anterior maxilla. This new concept of bone-driven soft tissue transformation may serve as an alternative for soft tissue augmentation in instances where tissue thickening is needed. However, the retrospective nature of the study and the lack of a control group or information of the long-term outcome of the procedure, as well as the multiple used methods that makes highlighting the contribution of each of the methods difficult - i.e. the tenting screw or pericardium membrane, are limitations of the study. Ideally, a prospective clinical trial with a control group is needed to assess whether this technique is in fact an improvement in handling gingival recession for implants placed in the esthetic zone as compared to standard surgical methods.

Perimplant Soft Tissue Considerations in the Esthetic Zone

Perimplant Soft Tissue Considerations in the Esthetic Zone

Stable soft tissue and underlying osseous architecture ensure long term success and longevity of implant based restorations, more so in the esthetic zone. This paper analyzes the position of periimplant soft tissues which is largely determined by biological factors like periodontal bio form, the biotype, biological width, the osseous architecture which in turn determine the position of the gingival margin and the interdental papilla. The adequacy of keratinized gingiva and its relevance to implant based restorations has also been discussed.

Esthetic concerns apply when the implant restoration and the surrounding soft tissues are visible during daily functional activities and in social settings. The increasing use of dental implant therapy to replace missing teeth in the esthetic zone underscores the importance of evaluating esthetic success. However, scientific literature describing reproducible esthetic parameters is considerably insufficient (Belser et al. 2004). In the esthetic zone, success is highly dependent on the long-term esthetic results that can be achieved. Optimally, the goal is to match the peri-implant soft tissue with the soft tissue of the adjacent natural teeth; the implant crown should blend naturally in size, contour and shape with the adjacent teeth (Meijer et al 2005). Yet, the most unpredictable determining factor in establishing esthetics is peri-implant soft and hard tissue support. Not only do clinicians have to consider existing tissue architecture, another important factor is the surgical positioning of the implant and subsequent remodeling process of the bone (Cardaropoli et al 2006).

Correlation between facial form and buccal corridors and its influence on smile esthetics

Correlation between facial form and buccal corridors and its influence on smile esthetics

orthodontically treated group. The large difference between the results of this study and the findings of Rigsbee can be attributed to the fact that these authors measured the buccal corridor by Hulsey's method (Peck and Peck, 1995) considering the distance between the maxillary canines as the lateral limit of the maxillary arch. The mean value of the percentage of the buccal corridor with the total smile width as found out by Ritter et al. (2006) was 19.20%. Our study is in accordance with their study wherein the mean value of the percentage of the buccal corridor with the total smile width was found out to be 19.98%. There was no statistically significant difference between the overall means of percentage of buccal corridor width and total smile width in esthetic smiles as evaluated by the evaluators and the overall mean of the percentage of the buccal corridor width and total smile width of the sample selected which is representative of normal population (Table 5). This means that the esthetic smiles were judged to be "esthetic" on the basis of other criteria such as the lip line (Hulsey, 1970; Johnson and Smith, 1995; Ricketts, 1982; Kageyama et al., 2006; Dong et al., 1999; Peck et al., 1992), smile line (Frush and Fisher, 1958; Hulsey, 1970; Tjan et al., 1984; Zachrisson, 1998; Miller, 1989), smile symmetry (Hulsey, 1970; Graber, 1966; Miller, 1989), upper lip curvature (Hulsey, 1970; Sabri, 2005; Mathews, 1978), dental and the gingival components. (Sabri, 2005; Mathews, 1978; Lombardi, 1973) This is a significant finding because it can conclude that in a normal population, width of the buccal corridor does not play a significant role in smile esthetics. Therefore it can be stated that the width of the buccal corridor does not affect smile esthetics

The role of inflammation in adipocytolytic nonsurgical esthetic procedures for body contouring

The role of inflammation in adipocytolytic nonsurgical esthetic procedures for body contouring

Although the scientific literature is generally favorable to this therapeutic approach for the treatment of localized fat, more clinical or experimental research is needed to validate the effective participation of inflammatory pathways in the lipo- lytic process triggered by adipocytolytic esthetic procedures. Although this study is the first review to confront clinical and basic research about the adipocytolytic procedures, it is not possible to propose a mechanism of action to explain the influence of inflammation in adipocytolytic process. However, the present integrative review plays an important role in medical practice based on evidence, to improve the

CAD-CAM  Implants in Esthetic and Reconstructive Craniofacial Surgery

CAD-CAM Implants in Esthetic and Reconstructive Craniofacial Surgery

A question not yet addressed by any investi- gation is the behaviour of the soft tissues after implant insertion. In theory, different ways are possible. Soft tissue could flow symmetrically around the implant, its thinning being depen- dant on the amount of stretching and on mate- rial properties. On the other hand, displacement into “favourite” regions could occur. As the behaviour is not known yet, evaluation of soft tissue reaction will be a major task in the fu- ture. This should improve implant design as the major task in esthetic surgery is to restore facial contour and not the underlying bone. Simu- lation software has been developed and it will be evaluated in the near future ( BERTI et al.
