Immediate implant placement

Chang-Hun Han, Kwang-Bum Park, Francesco Guido Mangano
OBJECTIVE: In the anterior regions, the resorption of the buccal bone after tooth extraction leads to a contraction of the overlying soft tissues, resulting in an esthetic problem, particularly with immediate implant placement. In the socket shield technique, the buccal root section of the tooth is maintained, to preserve the buccal bone for immediate implant placement. The aim of this prospective study was to investigate the survival, stability, and complication rates of implants placed using a "modified" socket shield technique...

PURPOSE: The aim of the present study was to analyze the alveolar bone morphology of the upper first and second molars. This analysis aims to evaluate the morphology of a hypothetical postextractive site in the upper molar area to diagnose the possibility of immediate postextraction implant placement. MATERIALS AND METHODS: Cone-beam CT scans of 100 patients were examined. The measurements were made using a dedicated 3D software. Reference points were identified to allow clear and repeatable measurements...

PURPOSE: To describe a rare case of odontogenic brain abscess. MATERIALS AND METHODS: A healthy, 35-year-old male had two dental implants placed in a simultaneously augmented maxillary sinus. One implant failed and the patient developed a maxillary sinusitis that failed to improve following antibiotic treatment at home. The neglected sinus infection led to formation of a brain abscess. The patient was hospitalised only when he had pan sinusitis with neurological signs...

BACKGROUND: For prolonged ischemic priapism, outcomes after distal shunt are poor, with only 30% success for priapic episodes lasting longer than 48 hours. AIM: To present a novel, glans-sparing approach of corporal decompression through a penoscrotal approach for cases of refractory ischemic priapism (RIP) after failed distal shunt procedures. METHODS: We describe the technique and present our initial experience with penoscrotal decompression (PSD) for treatment of RIP after failed distal shunt...

PURPOSE: The aim of this study was to evaluate the buccopalatal volumetric tissue change that occurs following flapless single-tooth immediate extraction placement in the esthetic area and to analyze the role of four different variables. MATERIALS AND METHODS: Patients in need of a single-tooth replacement in the anterior maxillary or mandibular area (premolar to premolar) were recruited for the study. Patients were treated using four different therapeutic modalities: group 1 (healing abutment), group 2 (healing abutment + bone graft), group 3 (provisional restoration), and group 4 (provisional + bone graft)...

PURPOSE: The purpose of this study was to retrospectively compare long-term outcomes for immediately loaded tilted and axial implants placed in the posterior region of the edentulous maxillary arch. MATERIALS AND METHODS: Data obtained from a 5-year prospective study designed to assess clinical outcomes following immediate loading of implants with screw-retained fixed restorations in the edentulous maxillary arch were retrospectively reviewed. Where insufficient alveolar bone was available for axial placement of the posterior-most implant on each side of the arch, tilted placement was employed...

PURPOSE: The aim of this study was to clinically and radiographically compare the trephine core procedure and the bone-added osteotome sinus floor elevation technique in the augmentation of the sinus floor. MATERIALS AND METHODS: A single site in each subject requiring sinus augmentation where the residual bone height was ~4 mm was randomly allocated to either the trephine core procedure or the bone-added osteotome sinus floor elevation technique. Measures of bone fill and bone height were also acquired through scans from cone beam computed tomography obtained before the sinus augmentation procedure (baseline) and before implant placement at approximately 6 months postoperatively...

PURPOSE: The objective of this study was to assess whether long-term implant survival rates and bone loss in patients with moderately controlled type 2 diabetes is similar to the rates reported in the nondiabetic population. MATERIALS AND METHODS: This retrospective observational study utilized patient medical records from a general practitioner's dental office. The records of patients who had moderately controlled type 2 diabetes with hemoglobin A1C (HbA1c) up to 8% and glucose level below 150 mg/dL were reviewed, as patients with HbA1c up to 7% are considered to be well-controlled type 2 diabetes...

BACKGROUND: Numerous studies indicate implants placed immediately after extraction or with minimally invasive procedures have excellent long-term success and survival rates. There is general agreement that implants must be stable after implant placement. This study evaluated implant stability changes from the time of implant placement to second stage (prior to restoration). Resonance frequency analysis (RFA) was determined for two commercially available units (Osstell, Osstell USA, Columbia, MD and Penguin, Penguin Integration Diagnostics, Sweden)...

OBJECTIVES: We assessed the transventricular placement of porcine small intestinal submucosa (SIS) stent valves in a juvenile sheep model at the 3-month follow-up evaluation. METHODS: We constructed a pulmonary stent valve by suturing a porcine SIS bicuspid valve into a bell-shaped 'Z' nitinol stent and implanted 7 SIS stent valves transventricularly in the pulmonary position in 7 sheep. The function of the stent valves was assessed using a pulsatile flow simulation system in vitro...

This article presents an overview of intramuscular gluteal augmentation involving primary and secondary augmentation with implants. Although gluteal augmentation is a well-studied procedure, few reports have described the intramuscular technique or this technique in association with lipofilling. This article presents experience with a combined technique; this recent innovation combines placement of an anatomic silicone gel implant underneath the gluteus maximus and immediate fat grafting. Primary and secondary gluteal augmentations using implants resulted in satisfactory outcomes...

Anatomical variations often present a challenge in the placement of an implant in its optimal location. A ridge split procedure, which had been recommended for narrow alveolar ridges, has recently undergone a number of modifications, making the procedure simpler and providing more predictable outcomes. This article reports the 3-year follow-up of 2 implants placed using a ridge split procedure with a piezoelectric surgical unit for the rehabilitation of the mandibular posterior ridge.

Periodontal plastic surgery comprises an increasing part of clinical periodontology. Clinical trials have traditionally used professionals to judge esthetic outcome, and few studies have addressed patient needs and requests (true end points). Development of universally accepted and validated methods for professional esthetic assessment, together with standardized questionnaires for patient-perceived outcome, may help to provide better insights into the true needs and benefits of periodontal and implant-associated plastic surgery...

OBJECTIVES: To address the following focused question: "Does the horizontal distance between two adjacent implants inserted in the anterior maxilla affect the inter-implant mucosa fill?". MATERIAL AND METHODS: A comprehensive literature screening was performed in MEDLINE and Cochrane databases from January 1, 2000 until July 1, 2017. Clinical human studies including ≥10 patients treated with at least two adjacent implant-supported crowns in the anterior maxilla with a minimum of 12 months of follow-up were searched...

STATEMENT OF PROBLEM: Immediate placement and provisionalization of implants in fresh sockets has been previously demonstrated to be a predictable treatment in the restoration of non-recoverable teeth in the anterior regions of the maxilla. PURPOSE: This article reports a clinical case in which an immediate implant placement protocol was used in combination with two distinct and sequential grafts (bovine bone and connective tissue, respectively) followed by immediate implant provisionalization using the patient's crown of an extracted tooth...

The growing interest in minimally invasive implant placement and delivery of a prefabricated provisional prosthesis immediately, thus minimizing "time to teeth," has led to the development of numerous 3-dimensional (3D) planning software programs. Given the enhancements associated with fully digital workflows, such as better 3D soft-tissue visualization and virtual tooth rendering, computer-guided implant surgery and immediate function has become an effective and reliable procedure. This article describes how modern implant planning software programs provide a comprehensive digital platform that enables efficient interplay between the surgical and restorative aspects of implant treatment...

When planned and implemented appropriately, single-unit implant dentistry in the smile zone can be an excellent alternative to attempting to save a failing natural tooth. Historically, implant success has revolved around assessment of osseointegration and the healing of bone around the implant, without much regard for esthetics upon completion. As implant dentistry has evolved, the expectations of both restoring clinicians and patients have expanded to emphasize the esthetic outcome as well as faster treatment with immediate implant placement...

Introduction: Von Willebrand Disease is the most common inherited bleeding disorder. In the general population, 1/8000 patients are affected. Primary hemostasis (platelet adhesion) and coagulation (protection of Factor VIII) are altered. Among several bleeding symptoms, these patients suffer from excessive bleeding of oral mucosa and dental management requires a close collaboration between haematologists and oral surgeons. Materials & Methods: Guided implant surgery can be used to increase the accuracy of implant placement and to reduce the overall morbidity of this surgical procedure by using a flapless surgery technique...
