SMILE REHABILITATION IN ANTERIOR AESTHETIC ZONE USING BASAL IMPLANT

Aesthetics are one of the primary goals of restorative care. Teeth that are traumatized in the anterior maxilla usually avulse or require extraction due to fractures. Rehabilitation is challenging in such a therapeutic state since it presents several anatomical and aesthetic issues. There are circumstances in which traditional implant placement is problematic. There must be enough bone for implant placement to be uneventful and successful. Other surgical therapies may be necessary in addition to implant placement for certain operations, such as extensive grafting, direct or indirect sinus lifts, and nerve lateralization. Certain procedures are required for these operations but are not always achievable. Because single-piece basal implants provide immediate temporization and loading while receiving adequate anchoring from the basal cortical bone, they have been extensively used to rehabilitate resorbed ridges. This case report demonstrates the placement of the basal implant in the anterior zone.

Literature Review Regarding the Applicability and Clinical Outcome of Basal Implant

Basal implants and their importance in clinical Dentistry: Literature review

Background: Basal implants, also known as cortical implants, have a history dating back to the mid-20th century. Although they are not as well known or widely used as conventional dental implants, they have been gaining relevance in dentistry in recent years due to their effectiveness in specific clinical situations. Objective: evaluate clinical effectiveness, analyze their indications, contraindications, examine complications and success rate. Methods: the research was structured based on a search tree (PubMed, Google Scholar, ProQuest, Scopus), with keywords such as: Basal Implant. The languages: English, Portuguese and Spanish were used as limiters; open access articles, systematic reviews, meta-analysis, randomized clinical trials, case reports. We established a secondary selection based on the title and summary of the articles according to the objective of the study.Results: The initial search showed 3,099 studies whose title was related to the search patterns, of which 3,029 articles were excluded based on their title and abstract, thus resulting in 70 potentially relevant articles. After reading, 21 articles that did not meet the inclusion criteria were excluded: repeated. In this way, 49 articles were finally selected to carry out this review. Conclusions: Dental implants offer significant benefits in oral functionality, facial aesthetics, self-esteem and long-term health. However, there are important considerations that encompass postoperative care, costs, insurance coverage, and access to these treatments.

Syncrystallization aka intra-oral welding for rehabilitation of basal implants: A case series

Dental implant rehabilitation has become a common treatment modality. Attempts to increase the predictability and success rate of implants are constantly been advocated. Syncrystallization/ Intra-oral welding is one such method that has the potential to enhance treatment outcomes. Welding the implants together not only favors undisturbed healing but also creates even distribution of forces. A case series is presented demonstrating the use of intra-oral welder to create splinting of dental implants for rehabilitation of full mouth and segmental rehabilitation. Immediate implant placement was performed in the cases followed by intra-oral welding. The welding technique has proven to be effective for immediate stabilization and loading of dental implants.

Basal Implant - A Boon to Immediate Implant Loading: A Case Report

The purpose of this article was to report a case of rehabilitating a patient involved in a road traffic accident using 10 single piece basal implants which were functionally loaded with a mandibular cement-retained fixed partial denture. Great outcomes were achieved with immediate loading implants. They can be inserted both into the healed bone and also the extraction sockets. Their implantation in bone of poor quality is made possible owing to their structural features. This makes basal implants the best choice over conventional implants in accident cases where the bone is irregular and has multiple defects. In cases where alternative treatment plans involve uncertain augmentations basal implants should always be the first choice. The basal implantology technique resolves all the problem related to traditional crestal implantology.

An Evaluation of the Efficacy and Acceptability of Basal Implants in Traumatically Deficient Ridges of the Maxilla and the Mandible.

Background and objective Rehabilitation of edentulous jaw areas is a complex procedure that has witnessed numerous advancements in technique and materials for better functional and aesthetic outcomes over the years. Dental implants have emerged as a cutting-edge, cost-effective, and non-invasive alternative to traditional removable partial dentures (RPDs), fixed partial dentures (FPDs), and full dentures. In this study, the basal implant was tested in traumatically deficient ridges on the mandible and the maxilla to determine its effectiveness and acceptability. Materials and methods The purpose of this research was to determine whetherbasal implants might be successfully used to restore traumatized ridges in the maxilla and mandible. Eleven individualsaged 20-55 years participated in the trial, and a total of 30 implants were used. All patients were evaluated for pain, soft tissue health around the basal implant, and patient satisfaction, with follow-ups on the third dayand at threeand six months postoperatively. Results The mean pain score measured using the visual analog scale(VAS)of patients during follow-ups was 2.00 ±1.15 on the third day, 0.40 ±0.84 at three months, and 0.00 ±0.00 at six months postoperatively. The mean gingival index score of patients was 1.30 ±0.48 on the third day, 0.10 ±0.31 at three months, and 0.00 ±0.00 at six months postoperatively. The mean patient satisfaction score was 34.77±5.54 on the third day, 41.11 ±6.27 at three months, and 40.7 7±10.91 at six months postoperatively. The mean immediate postoperative marginal bone levelwas 12.33 ±2.26 mm, and it was 10.85 ±2.29 mm after six months postoperatively. The mean preoperative crestal bone level was 10.76 ±1.77 mm and it was 9.70 ±1.79 mm after six months postoperatively. Conclusion Due to the fact that basal implantology does not involve extensive augmentation procedures necessary for the placement of conventional implants, it plays an important role in the rehabilitation of edentulous maxillary and mandibular arches, especially intraumatic, moderate to severely atrophic maxillary and mandibular arches.

Prosthetic rehabilitation with implant-supported fixed prosthesis in a completely edentulous patient: A clinical report

To present clinical strategies for prosthetic rehabilitation of completely edentulous patients using immediate-loading basal implants.A 58-year-old female patient was referred to the Department of Prosthodontics for restoration of her completely edentulous maxilla and mandible with a fixed full-arch implant-prosthetic rehabilitation. Since the patient lacks adequate bone in the posterior maxilla and is not willing to undergo a removable interim prosthesis, an immediate loading protocol along with 8 single-piece basal implants, including 2 pterygoid implants in the maxillary arch and 6 single-piece basal implants in the mandibular arch, was selected as the treatment option, followed by an acrylic provisional restoration. Four months later, a definitive fixed implant-supported prosthesis was delivered.This treatment strategy may be considered for rehabilitating patients with atrophic ridges demanding fixed provisional prostheses throughout the healing period and can be employed even in immediate implant placement after extraction.

Segmental Rehabilitation of Partially Edentulous Sites with Basal Cortical and Conventional Implants – A 1 Year Clinical Trial

Rehabilitation of atrophied/resorbed edentulous jaws by placing implants is a challenging procedure. Although various bone augmentation procedure like ridge augmentation, sinus lift is in practice but it may lead to the morbidity of donor’s site. Sometimes patient is not willing for such extensive surgical procedures. In such cases Cortical/basal implants is a viable treatment option. Basal implants gives support from the basal bone area which usually remains free from the infection and less prone to resorption. This study was undertaken to assess clinically and radiographically the bone levels in rehabilitation of immediate loading and delayed loading in opposite arch in an occlusion for a period of 1 year. After placing the implants, immediate loading was done within 72 hours for basal implants and conventional implants were placed in the lower partially edentulous sites.

Rehabilitation of Atrophied Anterior Mandible with Basal Implants: A Case Report

Basal implantology also referred to as bicortical implantology is considered to be a modern implantology system which utilizes the basal cortical portion of the jaw bones for retention of the dental implants, which are uniquely designed to engage within the basal cortical bone areas. In the present case, a 44-year-old healthy male patient reported to our department with grade III mobile 32, 33. After careful examination and treatment planning cortical implants with immediate prosthetic rehabilitation was initiated. The teeth were extracted atraumatically and two smooth surface cortical implants were placed into the extraction sockets followed by prosthetic rehabilitation using metal ceramic crowns. IOPA radiographs and CBCT were taken preoperative and immediate postoperative. The patient and operator compliance after placement of implant and prosthetic rehabilitation were analysed using a 10-point patient assessment scale. Cortical implant therapy has several advantages, it allows placement in bone that is deficient in height and width, reduced treatment length, reduced number of operations, immediate loading and better patient compliance.

Evaluation of Immediate Functional Loading with Single Piece Implants

Introduction: In recent years, implantology has increasingly advocated the concept of immediate loading, even with single implants. It is defined as the placement of a prosthetic restoration within 48-72 hours after implant placement. Among the other advantages of immediate loading like overall treatment reduction in timing, with function, cosmetic and psychological benefits for the patient. This case described a new surgical concept and a technique to fabricate screw-retained provisional crowns for immediate loading of free-standing single tooth implants. Hence the aim of this study is to evaluate immediate functional loading with single piece implants Materials and Methods: For rehabilitation with basal implants in sites after immediate extraction, a 2-mm twist drill, the first cortex (alveolar) was drilled and then drilling was continued till the basal cortex (nasal floor/sinus floor/lingual cortex/pterygoid bone), which was perceived as a dip. For rehabilitation with compressive screw implants in healed edentulous sites, the compression screw implants in the upper and lower jaw were inserted with the primary aim of achieving stability through compression of trabecular bone along the vertical (endosseous) axis of the implant. Frequency tables and chi square tests were used to analyze the data. Results: There were 30 patients with 76 implants present and assessed for this study. The mean age of the participants was 47.43±16.93. In the study participants, 30% of the participants had hypertension, 20% had diabetes mellitus and 20% had smoking habit. BCS and Compressive type of implants were both used in the study. In 51.32% sites, BCS implants were used and 48.68% sites Compressive type implants were used depending on the clinical situation. For the success of the implant, many criteria was assessed such as Implant stability quotient, mid-buccal gingival level and inter proximal gingival papilla, absence of complications (pain, discomfort, infection, bone loss and mobility). Results showed that there was a significant association found between diabetes mellitus with mobility, bone loss and discomfort. Contrastingly there was no association between smoking habit and any of the complications affecting the success of the implant. This showed that systemic disease plays a major role in the success of the implants. Conclusion: The high cumulative implant survival rate for the devices and the technology of the Strategic Implant® indicates (within the limitations of this study) that the immediate functional loading concept with cortically anchored implants or implants providing corticalization of spongious bone for the rehabilitation of partially edentulous segments and for single-tooth replacement in maxilla and mandible can be a viable concept even in cases where extractions of teeth were done simultaneously.

Assessment of insertion force for the placement of cortical implants in various anatomic sites in dried human skulls.

Dental implant treatment is an excellent option for prosthetic restoration that is associated with high success rates. Implant stability is essential for a good outcome. The basal bone implants are usually placed in poorly atrophied basal bone areas. To determine the stability during insertion in bones by measuring the torque using a wrench. To obtain the number of cortical engagements via stimulating concerned anatomical location in jaws. The study was designed as an ex vivo study. In case of basal implants, the integration of the implants is in stable cortex. Such a stable engagement is achieved by stimulation of certain areas in anterior maxilla such as anterior nasal spine, nasal floor, canine fossa, while posteriorly, maxillary tuberosity and pterygoid. In mandible the symphysis, parasymphysis, lingual cortex and retromolar pad areas were engaged. In this study, the above-mentioned areas were stimulated for the engagement of cortical bones using cortical implantology. Cortical implants of various sizes and tapers were inserted and analyzed for its bone quality and quantity. The stability of such implants was tested during insertion by measuring the torque with the use of a torque wrench instrument. Comparative observational study using standards of deviation. Within the limitations of this study, it may be concluded that there was a significant correlation between insertion force and diameter of implants when placed in jaws in a dried human skull model. The present study needs to be further conducted to establish the observational results completely and hence correlate the results with human studies.

Evaluación radiográfica retrospectiva de un año de la pérdida ósea marginal alrededor de los implantes basales y el impacto de múltiples factores de riesgo mediante análisis multivariado.

Background: Factors like medical and periodontal conditions, implant location and smoking can affect marginal bone loss (MBL) of basal implants. Objectives: The purpose of this study is to explore the association of MBL with multiple variables including gender, age, smoking status, diabetes, implant placement protocol, location of implant, and type of prosthesis. Material and Methods: A total of 156 single-piece basal implants (Dr. Ihde Dental AG in Gommiswald, Switzerland) were placed in 44 patients. Dental panoramic tomographs were obtained postoperatively and following a one-year of service to determine MBL on mesial and distal sides. The association of MBL with the multiple variables was analysed using the multivariate and the random forest analysis. Results: The mean mesial and distal MBL was 0.64 millimetres. None of the implants presented MBL exceeding 1 millimetre. All implants were retained without complications during the first year of service. The MBL was remarkably associated with the smoking status, diabetes, location of implant and implant placement protocol. Diabetes mellitus is the most vital parameter in predicting MBL. Conclusion: The mean MBL of all implants did not exceed the threshold of 1 millimetre during the first year of service. When placing implants in patients who smoke and have diabetes, care should be taken.

The Assessment of the Maximum Heat Production and Cooling Effectiveness of Three Different Drill Types (Conical vs. Cylindrical vs. Horizontal) during Implant Bed Preparation—An In Vitro Study

The aim of this experimental study was to verify thermal diffusion differences, by measuring the maximum temperature achieved with different drill shapes. Synthetic bone blocks of type I density made from solid rigid polyurethane (PUR) foam were used to perform the drilling procedures. The experiment was conducted at three different rotation speeds: 800, 3000 and 5000 rpm. Conical drills (with and without an internal cooling hole) were compared with horizontal drills and disc drills. The temperature during drilling for implant bed preparation was estimated with the use of thermocouples and an infrared (IR) camera. The temperature during drilling with disc cutters for lateral basal implants did not exceed 33 ∘C and the temperature decreased in proportion to higher drill speed. The results indicate that the tested design is safe and will not cause bone overheating.

Comparative Evaluation of Distribution of Stresses in Osseointegrated Crestal and Basal Implant in Zygomatic Region of Maxilla

Abstract Aim The aim of this study was to evaluate the distribution of stresses in osseointegrated crestal and basal implant in zygomatic region of maxilla and to identify the preferable implant option for better stress distribution. Material and Method The present in vitro study was performed to evaluate stress patterns in bone around basal and crestal dental implant under axial and oblique loading in maxillary zygomatic region with the help of a finite element analysis (FEA). To conduct this study, the following materials were used: computer software ANSYS, basal implants with dimensions 3.7 × 10 mm, and crestal implants with dimensions 3.7 x 10 mm. The amount of load transferred on the bone adjacent to the implant in an axial and transverse load of 100 N at 0 and 45 degrees, respectively, was placed on both types of implants. A three-dimensional (3D) scanner was use to generate 3D simulated model of basal and crestal implants. FEA modelling was generated that replicated the zygomatico maxillary region with special emphasis on bone architecture, bone density, angulation, width, and length of implant prototype. Further, material properties were defined for cortical bone, dense trabecular bone, low density trabecular bone, and titanium on the basis of Young’s modulus of elasticity. Results These values were used by FEA software (ANSYS) to generate a 3D mesh model of bone and implant. Finally, Von Mises (equivalent stress) (MPa) values on the implant were computed using FEA software. The values of maximum Von Mises equivalent stress on the implant collars, body, apex, and bony interface were obtained. Conclusion Maximum stresses were seen at the cortical bone with basal implant placed inside the bone. Stresses that are transferred more to the bone through implant promote bone remineralization. Maximum Von Mises stresses were observed on basal implant body. Thus, these greater stresses have the capacity to simulate mineralization in the cortical bone; this makes basal implant a suitable option for placement inside the cortical bone.

Basal Implant: A Remedy to Restore Resorbed Alveolar Ridges

AbstractThe conventional crestal implants are used only when there is adequate jawbone height and width. Results of conventional implants are good in patients with healthy bone at the time of treatment, but prognosis gets deteriorated when surgical augmentation of bone is included with implant placement. These augmentation procedures have surgical risks and are costlier to the patients. Patients with atrophied jawbones are given no treatment, until crestal implants are seen as the last option. In this article, the indications for basal implants and functional differences between basal implants and crestal implants have been discussed.Patients with extreme jawbone atrophy do not benefit from crestal implants. The basal bone is the (cortical) osseous tissue of the mandible and maxilla, and lies below the alveolar process, which has a relatively strong and no resorbing framework.Basal osseointegrated and basal cortical screw (BCS) are two types of implants designed to take anchorage from the cortical bone of the jaw. BCS implants have long shafts and can be placed immediately in the socket after extraction and provided with immediate loading within 72 hours of implant placement. Basal implants are also called bicortical or cortical implants as they utilize the cortical portion of the jawbones for anchorage and implant stability. The basal bone has better quality and quantity of cortical bone for retention of these unique and highly advanced implants. The other names for these implants are lateral implants or disk implants.

Stress Distribution in Cortical Bone around the Basal Implant - A Finite Element Analysis.

Aim:The aim of the study was to develop a model that represents a basal implant with stress distribution in the cortical bone on application of loads emulating masticatory forces.Materials and Methods:In this study, the stress distribution in the bone and the implant is evaluated by applying various loads that emulate the masticatory forces. The geometric models of cortical bone representing the premolar area and a basal implant model of the following specifications, longitudinal oval threaded pin (1.95 mm × 2.1/2.3 mm ø), height of the implant head (7.2 mm), and width of the implant head (3.5 mm) (BOI BS, IDHEDENTAL), were generated with Ansys software, and both the implant model and the bone model are superimposed to mimic the bone implant system as a unit.Results:Overall comparison of stress distribution on both implant shaft and implant neck showed that maximum stresses are located at implant neck irrespective of forces applied and minimum stresses are located at implant shaft. On overall comparison of stresses seen within the bone and the implant, it was observed that the maximum stresses were seen in the implant neck followed by the implant shaft followed by the bone interface.Conclusion:The present study concluded that the stress transmission is greatest during application of oblique load (70 N) followed by horizontal load (10 N) and the least by vertical load (35 N).
