Full Mouth Rehabilitation

Oral rehabilitation for a patient with severe loss of alveolar bone and soft tissue resulting from severe periodontitis presents a challenge to clinicians. Replacing loosening natural teeth with fixed prostheses supported by dental implants often requires either gingival surgery or bone grafting. The outcome of the bone grafting is sometimes unpredictable and requires longer healing time and/ or multiple surgeries. The presence of periodontal inflammation and periapical lesions often delay the placement of bone grafts as well as dental implants. Here we present a clinical case of a patient undergone full mouth reconstruction with implant-supported fixed prostheses. We demonstrated that early placement of implants (three weeks after extractions) with minimal bone grafting may be an alternative to conventional bone grafting followed by implant placement. We believe that primary stability during implant placement may contribute to our success. In addition, composite resin gingival material may be indicated in cases of large fixed implant prostheses as an alternative to pink porcelain.

Background/Aim. Flapless implant surgery has become very important issue during recent years, mostly thanks to computerization of dentistry and software planning of dental implants placements. The aim of this study was to compare flap and flapless surgical techniques for implant placement through radiographic and radiofrequency analyses. Methods. The experiment was made in five domestic pigs. Nine weeks following domestic pigs teeth extraction, implants were placed, on the right side using surgical technique flap, and flapless on the left side. Digital dental Xrays were applied to determine primary dental implant stability quality (ISQ). At certain intervals, not later than three months, the experimental animals were sacrificed, and just before it, control X-rays were applied to measure dental implants stability. Results. Radiographic analysis showed that peri-implant bone resorption in the first 4 weeks following placement implants with flap and flapless surgical techniques was negligible. After the 3 months, mean value of peri-implant bone resorption of the implants placed using flap technique was 1.86 mm, and of those placed using flapless technique was 1.13 mm. In relation to the primary dental implant stability in the first and second week there was an expected decrease in ISQ values, but it was less expressed in the dental implants placed using the flapless technique. In the third week the ISQ values were increased in the dental implants placed by using both techniques, but the increase in flapless implant placement was higher (7.4 ISQ) than in flap implant placement (1.5 ISQ). The upward trend continued in a 4- week period, and after 3 months the dental implant stability values in the implants placed using flap technique were higher than the primary stability for 7.1 ISQ, and in the implants placed using flapless technique were higher comparing to the primary stability for 10.1 ISQ units. Conclusion. Based on the results of radiographic and resonance frequency analyses it can be concluded that the flapless technique in surgical implants placemat, leads to better results.

Background. The immediate placement of a dental implant could represent an option treatment for the rehabilitation of a postextractive missing tooth socket to replace compromised or untreatable teeth, with the advantage of single-session surgery. In this way, the anatomy of the alveolar bone defect, the preservation of the buccal cortical bone, and the primary stability of the fixture represent the critical factors that consent a precise implant placement. Objective. This case report describes a novel fixture design for postextractive alveolar socket immediate implant. Methods. Two patients (25 and 31 years old) were treated for postextractive dental implant placement to replace both central upper incisor teeth with four implants. The residual bone implant gap was not filled with graft or bone substitute. The restoration was provided following a standard loading protocol by a cement-sealed prosthetic abutment. Results. Clinically, all implants positioned showed an excellent insertion torque. No postoperative complications were reported. At 6 months of healing, the buccal cortical bone and the implant stability were present and well maintained. Conclusion. The evidence of this study allows us to underline the possible advantages of this new fixture design for postextractive implant technique.

Abstract A variety of techniques and materials has been used to provide the structural base of bone and soft tissue support for dental implants. Alveolar bone augmentation techniques include different surgical approaches such as guided bone regeneration, onlay grafting, interpositional grafting, distraction osteogenesis, ridge splitting, and socket preservation. In the case presented, a technique was used to augment the alveolar bone three-dimensionally with autologous “bone rings” and immediate implant placement in a 1-stage procedure following teeth extraction. Bone rings (circular osteotomies) were outlined at the symphysis area using trephine burs, and a central osteotomy for implant placement was done before its removal. The rings were then removed and sculptured to fit the extraction socket; this was followed by screwing the implant through the ring, gaining its primary stability from the prepared basal bone.

Dental Aesthetics

Dental implants are made of medical titanium and perfectly fit into human bone tissue; the dental implant can last a lifetime. Not beeing living organic structures, there are no nerve endings, neither at the implant level nor at the artificial crown level. The use of quality implants by an experienced implantologist, assisted by advanced technology, transforms the treatment with dental implants into the medical-surgical act with the highest success rate among dental and even medical treatments.Through the complete replacement of the tooth, including the root, can artificially reproduce the function of the natural tooth, with a strong and stable base. The implant crown, made of aesthetic materials (porcelain, zirconium) and anchored to it by means of the prosthetic abutment, will be surrounded by a healthy and aesthetic gum. Especially if the prosthetic abutment (the connecting element between the implant itself and the artificial crown) will be made of zirconium - natural light will cross ceramic layers, similar to enamel and dentine, offering a white of envy and glitter to the smile. Around the porcelain crowns (whole ceramics or zirconia ceramics) the gingiva will conform healthily, without the slightest sign of inflammation. These elements, the white of the teeth and the pink of the gums define the concept of dental aesthetics. The main problems that diabetic patients may encounter, are gingival inflammation and periodontal disease, dental mobility and tooth loss. When a dental implant is influenced by the type of diabetes, its failure rate is higher in patients with type 1 diabetes than in patients with type 2 diabetes. The study included a number of 56 patients, who presented themselves for performing an implant. Of these, 7 patients did not perform an implant. Diabetes mellitus defines a chronic metabolic disorder, which may have multiple etiopathogenesis, characterized by changes in carbohydrate, lipid and protein metabolism. Stability of the implant in the bone, immediately after implantation is crucial for the success of the treatment; this immediate stability is called primary stability and is purely mechanical in nature.

Dental implants provide a strong foundation for fixed or removable prosthetic teeth that are made to match natural dentition. It has become an ideal method of oral rehabilitation after missing natural dentition has been recognised as a reliable tool for dental reconstruction and aesthetics. Marginal bone loss is characterized by a reduction in bone loss is characterized by a reduction in bone level both vertically and horizontally. The levels at which dental implants are placed include sub-crystal, equi-crestal, and supra-crestal. The crestal levels affect bone height significantly. Failure to do so will lead to peri-implant bone loss which will affect the implant function and ultimately implant failure. A retrospective study was conducted based on a university setting. 615 patients with 1141 implant sites were reviewed from June 2019 to March 2020. Excel tabulation and SPSS analysis were done for data analysis. There was a statistically significant difference between the variables that included tooth region, crestal relation and site (jaw)—[p-value<0.05] The most common crestal relation of implant placement is equi-crestal implant placement. The assessment of trends of implant placement in relation to crestal bone level shows that equi-crestal implant is the most preferred crestal relation of implant placement in Saveetha Dental College.

Hypodontia often leads to limited bone availability of the alveolar ridges. Oral rehabilitation of severe hypodontia patients is challenging. In this retrospective study, we evaluated the functional and aesthetic results after dental implants in hypodontia patients, corroborated by Albrektsson implant success criteria. Over a period of 15 years (2000–2015), a total of 43 patients were diagnosed with hypodontia and 165 dental implants were inserted. Six patients who received 10 implants were lost in the follow-up. We examined 155 implants in 37 patients between December 2015 and May 2017. Besides family history, patients evaluated the general satisfaction, functionality, and aesthetics of the implants. Study subjects were between 17 and 44 years old (mean ± SD: 21.4 ± 5.6). Hypodontia patients were missing one to five teeth (n = 28), whereas patients diagnosed with oligodontia (≥6 missing teeth, n = 9). In this study, 24 patients (64.9%) with hypodontia had a positive family history; the remaining 13 patients had no family member with hypodontia. The final follow-up time ranged between 5 and 189 months after implant placement. Orthodontic treatment was performed in 32 patients (86%) before implant placement. Rehabilitation resulted in 62% of the cases being treated with 1–2 implants and 38% treated with 3–15 implants. However, out of 155 inserted dental implants, 18 implants failed to meet Albrektsson criteria, under which two implants were removed. Only autografts were used for bone augmentation with 97 implants. More than two-thirds of the patients showed high general satisfaction and masticatory function (69.4%) as well as phonetic ability (80.6%). The aesthetic outcome was rated as excellent by 17 patients (47.2%). The findings emphasize the importance of interdisciplinary treatment of hypodontia, leading to a satisfactory, functional, and long-term fixed prosthodontics using dental implants.

Long-term stability of a dental implant depends on various factors, one among them is proper position within the alveolar bone. Pre-operative thorough examination of the surgical site is preliminary step while planning dental implants. Conventional techniques such as Intra-Oral Periapical Radiograph and Ortho Pantamogram sometimes not sufficient and clinical scenario always surprises the surgeon. Later advent of Cone-Beam Computed Tomography alleviated this problem to some extent but there are some clinical situations such as resorbed ridge where better visualisation is needed. This led to the innovation of rapid prototyping techniques for the fabrication of three-dimensional complex structures. This technology has numerous applications from the development of an instrument, 3-D printed anatomical models to the fabrication of 3-D printed tissues for regeneration procedures. A 3-D printed model is much more useful than plaster models in many aspects such as demonstrating anatomical structures, better treatment planning, and better understanding for the patient. Hence, this case series focuses on the use of 3-D printed models in the placement of dental implants.

Osteotome Sinus Floor Elevation

This case report discusses osteotome sinus floor elevation (OSFE) and immediate placement in 2 stages in severely resorbed alveolar bone height in which multiple implant placement is not otherwise feasible due to a lack of initial stability. The first implant placed using OSFE without bone grafting prepares the adjacent resorbed sites for further implant placement in the sinus areas, which allows for better initial stability and early functional loading. This process avoids the conventional extensive lateral approach for sinus lifting and bone grafting procedures even in extremely resorbed alveolar bone.

Objective: The aim of this retrospective study was to evaluate the outcomes of secondary alveolar bone grafting and late secondary alveolar bone grafting in 66 unilateral cleft lip and palate patients. Materials and Methods: The total patients were 66 unilateral cleft lip and palate patients, out of which 19 patients underwent secondary alveolar bone grafting and 47 patients underwent late secondary alveolar bone grafting. Autogenous anterior iliac crest cancellous bone graft was harvested and used for grafting the alveolar clefts. Radiographic assessment based on Enemark’s scoring according to the marginal bone levels was done on the intraoral periapical radiographs taken 6 months after performing the surgery. Results: Twelve (63%) out of the 19 patients on whom secondary alveolar bone grafting was done achieved score 1 (optimal marginal bone levels), whereas only 12 (25%) out of the 47 patients achieved score 1 amongst the late secondary alveolar bone graftings. Overall results showed, probability, P = .034 (statistically significant). Conclusion: This study reaffirmed the fact that alveolar bone grafting when done in preadolescent age group (secondary alveolar bone grafting) gives better results in terms of marginal bony consolidation and maintaining the continuity of the alveolar arch, but the late presentation (late secondary alveolar bone grafting) should not be the refusal criteria for performing the alveolar bone grafting. Although the latter patients may not be rewarded in terms of bony consolidation as much as the preadolescent patients the potential of successful surgery in them still exists in terms of providing a platform for the dental implant placement, improvement in the soft tissue symmetry and aesthetics of the face.

ABSTRACT Objective: The aim of the present ex-vivo study was to evaluate the effect of the vertical placement angle of mini-implants on primary stability by analyzing maximum insertion torque (MIT). Methods: Mini-implants were placed in 30 human cadavers, inserted at either a 90° or 60° angle to the buccal surface of the maxillary first molar. Out of 60 self-drilling mini-implants used, half were of the cylindrical type and half were of the conical type. Primary stability was assessed by means of measuring the MIT. Data were subjected to analysis of variance (ANOVA) and Newman-Keuls tests. A significance level of 5% was adopted. Results: The MIT was higher for both mini-implant types when they were placed at a 90° angle (17.27 and 14.40 Ncm) compared with those placed at a 60° angle (14.13 and 11.40 Ncm). Conclusions: MIT values were differed according to the vertical mini-implant placement angle in the maxillary posterior area. Regardless of the type of mini-implant used, placement at a 90° angle resulted in a higher MIT.
