Correlation Between the Orientation of the Nasopalatine Canal and the Upper Central Incisors: A Comparative Radiological Study Using Cbct.

During implant placement in the upper anterior region, the nasopalatine canal (NPC) is a frequently encountered anatomical structure. It connects the nasal and oral cavities and contains critical blood vessels and nerves. Despite its clinical relevance, no study has yet assessed the orientation of the NPC in relation to the upper central incisors to aid in optimal implant positioning.

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

Creating an osteotomy through a remaining root to place a dental implant is 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, as well as 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.

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.

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.

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.

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).

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.

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.

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.

The Custom Alveolar Ridge-Splitting (CARS) Technique for Predictable Horizontal Ridge Augmentation in the Atrophic Anterior Maxilla: A Retrospective Case Series Study.

Implant-supported restorations have proven to be a predictable option for replacing missing teeth. In cases of inadequate bone quantity, the bone volume can be increased by bone augmentation procedures. Several factors can affect bone regeneration, including the morphology of the defect at the implant site.

A Novel Method for Immediate Implant Placement in Defective Fresh Extraction Sites.

Purpose: This study assessed a novel treatment protocol for immediate implant placement in defective fresh extraction sockets.

Materials And Methods: A single-arm clinical study was conducted including 12 fresh extraction sockets divided into two groups: those with intact and those with a deficient facial plate of bone. Hopeless teeth were atraumatically extracted, a vestibular access horizontal incision was made 3 to 4 mm apical to the mucogingival junction, a mucoperiosteal tunnel was created from the labial orifice of the socket, a slowly resorbing membrane shield was stabilized under the tunnel, implants were placed using a surgical guide, and a subepithelial connective tissue graft was harvested and secured over the membrane shield.

Expanded Clinical Applications of Narrow-Diameter Implants for Permanent Use.

This report discusses the expanded use of narrow-diameter implants (< 3.0-mm diameter) for permanent use and presents multiple clinical uses for supporting permanent restorations. The increased applications of narrow-diameter implants have expanded the options of treatment available to clinicians based on the patients' needs, desires, and limitations.

Technique Using a Novel Verification Guide for Complete Seating of Open-Tray Impression Copings.

The purpose of impression-taking is to attain the accurate transfer of intraoral information for extraoral use. It is a crucial step in performing a successful dental implant restorative procedure. To accurately replicate the implant position for adaptation of an abutment that will completely engage with the implant, a pick-up impression is taken with an impression coping.

Removal of a Dental Implant Displaced Into the Maxillary Sinus After Final Restoration.

Displacement of a dental implant into the maxillary sinus has become a more frequent occurrence due to a greater number of implant-supported prostheses being placed in the atrophic posterior maxillary area. In addition, dentists are increasingly placing implants into augmented maxillary posterior areas. Reasons for displacement of dental implants into the maxillary sinus may include poor bone quality or quantity, failure of a sinus augmentation procedure, and poor surgical technique.

Anterior Tooth Replacement with an Implant in a Grafted Alveolar Cleft Site: Case Report with a 10-Year Follow-up.

The aim of this report is to present a case with a 10-year follow-up of a single anterior tooth dental implant replacement with a xenogenous bone graft in a patient with a large bone defect associated with a cleft lip and palate. At 10 years postloading, the implant was healthy and well-integrated. Although the implant restoration appeared slightly intruded due to growth and development at that time, the patient was happy with the esthetic result and refused corrections of the uneven occlusal plane.
