Clinical Advantages of Implant Osteotomy through the Remaining Root in Mandibular Premolar Region.

The placement of a dental implant by creating the osteotomy through the remaining root can serve as a placement option that offers various advantages. These benefits include more precise drilling with reduced vibration in cases with limited available bone or with anatomical structures such as the mental foramen and inferior alveolar nerve in close proximity to the planned osteotomy, and facilitating the extraction of an ankylosed tooth following root canal treatment. This case report presents a detailed description of the surgical and restorative procedures involved in placing an implant in a mandibular premolar area.

A Modified Socket-Shield Technique: Simplifying the Root Sectioning Process.

Socket wall resorption leading to a loss of surrounding bone following tooth extraction has been documented in the dental literature. The use of various socket-shield techniques has been suggested as a solution to this issue. In these approaches, the tooth root is sectioned in two, and the coronal two-thirds of the buccal root is preserved in the socket.

A Less-Invasive Window Design for Lateral Wall Maxillary Sinus Augmentation for Single Implants.

Maxillary sinus window design is an important factor in sinus augmentation procedures, playing a key role in managing maxillary sinus elevation complications, avoiding the sinus septum, and providing lateral support for the graft material. A less-invasive window design in comparison to conventional maxillary sinus windows was introduced with an "I"-shaped window for single implant placement. However, drawbacks of this window design have included limited instrument accessibility to the anterior sinus and incomplete membrane elevation.

The Custom Alveolar Ridge Splitting (CARS) Technique for Predictable Horizontal Ridge Augmentation in the Atrophic Posterior Mandible: A Case Report.

The Custom Alveolar Ridge Splitting (CARS) technique was recently reported as a less-invasive treatment option for augmentation of the maxillary anterior area in cases where alveolar width deficiency exists due to bone resorption and remodeling. This technique creates an intraosseous defect to improve success when horizontal ridge augmentation is attempted. The purpose of the present case report was to demonstrate implant placement in an atrophic posterior mandibular site using the CARS technique.

The Customized Alveolar Ridge-Splitting (CARS) Technique Combined with Guided Bone Regeneration or Sinus Elevation Augmentation in Maxillary Deficient Ridges.

Various techniques have been proposed to regenerate deficient ridges after tooth removal, including guided bone regeneration, block grafting, distraction osteogenesis, and ridge splitting. However, these procedures are technique-sensitive and often present complications which prevent reconstruction of the deficient ridge and implant placement. In an atrophic anterior or posterior maxilla, these techniques often fail to produce satisfactory long-term outcomes due to the poor bone quality, pneumatization of the maxillary sinus, and the highly cosmetic patient demands.

Treatment of a Soft Tissue Depression with a Xenograft Bone Substitute at the Second Stage of an Implant Procedure: A Case Report.

Following the extraction of a compromised tooth, the edentulous alveolar ridge undergoes physiologic bone remodeling, which may create a bone volume too deficient for implant placement. Guided bone regeneration (GBR) provides a predictable treatment option to increase the alveolar bone volume for implant placement, but a soft or hard tissue deficiency may remain even after this augmentation procedure has been completed. These deficiencies can be especially challenging in the esthetic zone, where patient expectations and esthetics often determine the satisfaction of the treatment outcome.

Successful Implant Placement into a Site with Two Previous Failures: A Clinical and Histologic Case Report.

Implants present a predictable fixed option for patients who require tooth extraction. However, complications such as implant failure reduce the success of replacement implant restorations. A patient presented to the Department of Periodontology and Implant Dentistry (New York University College of Dentistry) with pain related to a broken implant-supported prosthesis.

A Retrospective Study of Implant Placement Lateral to the Inferior Alveolar Nerve (ILIAN) in Severely Atrophic Posterior Mandibular Ridges.

Currently, there are several techniques being used in the posterior mandible to increase alveolar bone height and width. However, each of these has potential complications and limitations. The purpose of the current study was to present the surgical technique and restorative considerations for implant placement lateral to the inferior alveolar nerve (IAN) in cases of severely atrophic edentulous posterior mandibles.

Ehlers-Danlos Syndrome in Prosthodontics, Periodontology, and Implant Dentistry: A Systematic Review of the Literature.

Ehlers-Danlos Syndrome (EDS) is one of the most common congenital connective tissue disorders, affecting the synthesis and production of collagen cells. The medical implications for joints, muscles, soft tissue, and blood circulation have been documented in the literature. Many oral manifestations are displayed in EDS patients, including gingival recession, lack of attached gingiva, early severe periodontitis, and dental anomalies and dental caries.

Clinical Considerations of Ehlers-Danlos Syndrome for Implant Dentistry: Two Case Reports.

Ehlers-Danlos Syndrome (EDS) is a group of congenital connective tissue disorders that commonly affect joints, muscles, soft tissue, and blood circulation in the affected population. Many oral manifestations are displayed in EDS patients that can include gingival recession, lack of attached gingiva, early severe periodontal disease, and dental caries. However, the literature is limited and oftentimes contradictory regarding dental implants in EDS patients.

Reconstructing Peri-implant and Papillary Soft Tissue in the Esthetic Area Using Interdental Tissue, a Tuberosity Connective Tissue Graft, and a Tunneling Approach: A Case Report.

Long-term survival of dental implants in both fully and partially edentulous patients has been proven successful, as reported in the literature. However, maintenance of soft-tissue quality and volume is often difficult due to the multiple surgeries involved in implant placement and the physiological resorption of bone after tooth extraction. Soft-tissue augmentation is frequently necessary to improve soft-tissue contour and can be done simultaneously with implant or abutment placement or following the final insertion of the implant-supported prostheses.

Regenerative Treatment of Advanced Peri-implantitis: A Retrospective Case Series with 3 to 15 Years of Follow-up.

The present case series evaluated implant survival and changes in bleeding on probing (BOP), probing depths, marginal tissue levels (recession), and bone levels following regenerative treatment of implants with advanced peri-implantitis. Forty-six implants with advanced peri-implantitis in 38 patients were treated with a regenerative protocol and evaluated for the above parameters at the final follow-up 3 to 15 years later. Patients returned every 2 to 3 months for maintenance and at the final evaluation.

Repair of a Non-Retentive Crown Over a Press-Fit Implant Placed 30 Years Prior: A Case Report.

Dental implant treatment has been proven to be a successful therapy to rehabilitate single, partial, and fully edentulous sites. Evidence shows that the use of implant-supported restorations is predictable and can deliver long-term success. However, discontinuation of implant systems can be challenging for prosthesis maintenance.

A Narrative Review of the Diagnosis, Etiology, and Treatment of Halitosis Over the Past Three Decades.

Although the term "halitosis" was first coined in 1874, people have become increasingly aware of this problem more recently during the COVID-19 pandemic due to extensive wearing of protective masks. In fact, following dental caries and periodontal disease, halitosis is the third most prevalent reason for patients going to the dentist. Due to multifactorial etiology, the diagnosis of halitosis requires a rigorous health/dental/social history, a clinical examination, and measurements.

Surgical Strategies Used to Successfully Re-implant an Implant that Failed Four Times at the Same Site: A Case Report.

Although implants have been shown to have high success rates, complications such as implant failure can occur. This presents a challenging dilemma for clinicians when attempting another implant placement in the failed site. The patient in this clinical case report presented with implant failure four times at the same site.

A Revised Peri-implantitis Classification Scheme: Adding Three-Dimensional Considerations to Facilitate Prognosis and Treatment Planning.

Historically, diagnosing peri-implantitis is done based on whether the disease is present, evaluated using the arbitrary thresholds of probing depths and bone loss. Using this approach as a tool to ascertain meaningful information regarding prevalence and treatment is limited. Efforts have been made to improve upon this, but to date, only one of these classifications has provided a simple method to communicate disease severity based on the amount of bone loss.

Dental implant failure rates in patients with self-reported allergy to penicillin.

Background: In a number of previous studies, patients with reported penicillin allergies have been documented to experience higher rates of dental implant failure than those who had not reported this allergy. The authors of this study aimed to determine whether an increased risk of implant failure is associated with patient-reported penicillin allergy and which antibiotic was administered.

Methods And Materials: A retrospective study was conducted through chart review of patients who received dental implants at the New York University College of Dentistry.

Long-term Results of Maxillary Full-Arch Reconstruction Using Transitional Implants: A Case Report With 20-Year Follow-up.

Because of their documented long-term success rates, dental implants have become a predictable treatment option to replace hopeless or missing teeth. However, full-arc transition from a hopeless dentition to a prosthesis supported by dental implants remains a challenge. One treatment option for this process is the use of transitional implants, an approach that allows for the transitioning of full-arch reconstructions from teeth to implant-supported prostheses without immediate loading the permanent implants or the need for provisional removable partial dentures.

Histologic Findings 8 Weeks After Customized Alveolar Ridge-Splitting Technique.

Different techniques have been introduced when replacement with an implant is planned after tooth extraction. The conventional approach consists of waiting 3 to 4 months before implant placement. However, many other options are available for implant placement, including immediate implant placement (IIP), IIP and immediate provisionalization (IIPIP), and early implant placement (EIP).

A Retrospective Study of Bone-Level Stability Around 335 Hybrid Implants Placed with an Immediate or Delayed Protocol.

This retrospective study evaluated 335 hybrid implants placed in edentulous ridges; 167 were placed with an immediate implant protocol (IIP) and 168 were placed with a delayed implant protocol. Radiographic bone level changes were measured 1 to 23 years after loading. The average bone loss between implant placement and second-stage loading was 0.

Improving Free Gingival Graft Success Around Implants Using a Completed Implant Restoration.

Keratinized mucosa around implants is considered essential for maintaining peri-implant health. Clinicians may find it necessary to augment keratinized tissue after implant loading when complications arise. Immobilizing the graft can be challenging when there is a complete absence of attached gingiva or when the vestibule is shallow creating an opportunity for muscle forces to move the graft.

Effect of alveolar ridge preservation on clinical attachment level at adjacent teeth: A randomized clinical trial.

Purpose: To test whether or not alveolar ridge preservation (ARP) changes the clinical attachment level (CAL) at adjacent teeth of extraction sockets after 6 months.

Material And Methods: Seventeen patients requiring bilateral tooth extractions of the upper molars were recruited. After tooth extraction, the sockets were randomly allocated to two groups applying a split-mouth design: (1) ARP using deproteinized bovine bone mineral containing 10% collagen (DBBM-C) covered by a collagen membrane and (2) spontaneous healing (control).

A New Concept of Safety Distance to Place Implants in the Area of the Inferior Alveolar Canal to Avoid Neurosensory Disturbance.

Inferior alveolar nerve (IAN) damage following implant placement is a severe complication that can compromise a patient's quality of life. Previous studies have suggested that a safety zone of 2 mm, if maintained, might avoid this problem. This retrospective study evaluates implants placed in closer proximity to the IAN without resulting in any postoperative neurologic complications and suggests a new concept of safety distance.

Accuracy of Cone-Beam Computed Tomography Versus Periapical Radiography Measurements When Planning Placement of Implants in the Posterior Maxilla: A Retrospective Study.

Unlabelled: Intraoral periapical (PA) radiography is commonly used for measuring the remaining crestal bone height when implants are treatment planned in the maxillary posterior region. A major drawback of conventional radiographs is that a 3-dimensional (3D) entity is compressed and superimposed on itself into a 2-dimensional (2D) image, which is often distorted. Conversely, 3D information can be extracted from computerized tomography.

Patient-Related Risk Factors for Maxillary Sinus Augmentation Procedures: A Systematic Literature Review.

The posterior maxilla has traditionally presented a challenge for successful placement of dental implants due to a combination of poor bone quality, ridge atrophy, and pneumatization of the sinus floor following tooth extraction. However, with the successful and predictable surgical outcomes reported in the literature, more clinicians and patients are choosing an implant-supported restoration in the edentulous posterior maxilla. Consequently, sinus elevation and augmentation have gained more popularity.
