Immediate dental implant

Firas A Jamil, Sahar Shakir Al-Adili
Many treatment modalities have been introduced for correction of deficient alveolar ridge width. Bone expansion through the ridge split procedure is one of them. This technique was initiated in order to overcome many problems that usually associated with grafting procedures. The present study evaluated the effectiveness of piezoelectric device in performing ridge split using single-stage approach and assessed the outcomes during a period of about 4 months after surgery. A total of 23 patients ages in range between 18 and 60 years underwent ridge split procedure with immediate insertion of dental implants...

BACKGROUND: Reconstruction of maxillary defects following tumor extirpation is challenging because of combined aesthetic and functional roles of the maxilla. One-stage reconstruction combining osseous free flaps with immediate osseointegrated implants are becoming the standard for mandibular defects, and have similar potential for maxillary reconstruction. METHODS: A woman with maxillary Ewing sarcoma successfully treated at age 9 with neoadjuvant chemotherapy, right hemimaxillectomy, and obturator prosthetic reconstruction presented for definitive reconstruction, complaining of poor obturator fit, and hypernasality...

As life expectancy increases, a larger number of elderly people require dental health care attention for implant-supported rehabilitation, with the aim of restoring the function and aesthetics of the oral cavity. Most of these patients have lost their teeth long time ago, causing a severe bone resorption and maxillary sinus pneumatization. Therefore, the current study aims to demonstrate, through the description of the clinical case, the treatment with zygomatic implants as an option for treating severely atrophic maxillas...

Dental implants with their increasing success rates and predictability of final outcome are fast becoming the treatment of choice for replacing missing teeth. Considering the success of immediate implant placement in reducing tissue loss and achieving good esthetic results, is making it a more popular treatment modality in implant dentistry. Understanding the management of gingival tissues in relation to implants to obtain maximum esthetics is of utmost importance. The use of provisional abutments and immediate temporization has a proven track record of their ability to produce optimal esthetics and to guide the tissue response during the healing phase...

Different parameters can be measured during dental implant insertion to determine the primary stability of the implant. The purpose of this retrospective study was to investigate whether a correlation exists between immediate implant insertion torque value (ITV) and implant stability quotient (ISQ) in nonmolar sites. A total of 59 implants in 52 patients were placed into extraction sockets. ITV was recorded at surgery, and ISQ was recorded at surgery and at follow up. Implants with higher ITV and/or ISQ were evaluated at 6 to 8 weeks...

AIM: To test whether or not soft tissue augmentation with a collagen matrix (VCMX) leads to a similar increase in ridge width around dental implants compared to the use of an autogenous subepithelial connective tissue graft (SCTG). MATERIALS AND METHODS: In 12 dogs, immediate dental implants were placed with simultaneous guided bone regeneration. Three months later, soft tissue volume augmentation was performed by randomly allocating three treatment modalities to these sites (VCMX, SCTG, sham-operated group (control))...

BACKGROUND: Over the last decades, dental implants have become increasingly popular in the prosthetic rehabilitation of patients. This has subsequently led to an increase of perioperative complications. Obstruction of the airway as a result of a floor of mouth hematoma after dental implant surgery is a rare but life-threatening complication. CASE REPORT: A 62-year-old man presented to the emergency department with a compromised airway caused by a hematoma in the floor of the mouth that occurred during dental implant surgery in the edentulous anterior mandible...

BACKGROUND: The dentitions of extinct organisms can provide pivotal information regarding their phylogenetic position, as well as paleobiology, diet, development, and growth. Extant birds are edentulous (toothless), but their closest relatives among stem birds, the Cretaceous Hesperornithiformes and Ichthyornithiformes, retained teeth. Despite their significant phylogenetic position immediately outside the avian crown group, the dentitions of these taxa have never been studied in detail...
