Summary:

Retrograde peri-implantitis (RPI) is defined as a clinically symptomatic periapical lesion that develops shortly after implant insertion while the coronal portion of the implant sustains a normal bone-to-implant interface. A 61-year-old male was screened and evaluated for three maxillary anterior implants placed 10 years previously. Evaluation included a thorough periodontal and dental exam, radiographs, and cone-beam computed tomography. Probing depths around all implants ranged from 2 to 4 mm with no bleeding on probing/mobility. The apices of implants #8 and #9 exhibited radiolucencies, and a draining fistula was associated with implant #8. Treatment consisted of sectioning and removal of the affected portion of the implants and collection of a specimen for histopathologic examination. Resection of the apical portion of implants is a viable treatment modality in the management of RPI.

Immediate Occlusal Loading of Osseotite Implants in the Lower Edentulous Jaw
<b>Objective:</b> This paper reports the results of a prospective multicenter clinical study on immediately fully occlusally loaded full-arch screw-retained prostheses with distal extensions (hybrid prostheses) supported by Osseotite implants inserted in edentulous lower jaws. <b>Method and material:</b> Sixty-two patients were enrolled in four clinical centers. Three hundred and twenty-five Osseotite implants were inserted and occlusally loaded according to an immediate loading protocol. The temporary…

Effect of Different Cementation Techniques on Retained Excess Cement and Uniaxial Retention of the Implant-Supported Prosthesis

Effect of Different Cementation Techniques on Retained Excess Cement and Uniaxial Retention of the Implant-Supported Prosthesis
The aim of the study was to identify the different techniques of cementation (half filling, practice abutment, and venting) that will reduce the amount of retained cement and the effect of these techniques on retention of implant supported prostheses. The venting and practice abutment techniques are suitable methods of reducing retained excess cement with optimal retention values.

Healing of Osseotite Implants- After 2 months

Healing of Osseotite Implants- After 2 months
A growing number of clinical studies show that early (2 months) and immediate loading protocols may be predictable. However, they are based on clinical stability only. The aim of this case report was to document the osseointegration status of two Osseotite implants after 2 months of healing in soft bone corresponding to type IV and subjected to two distinct mechanical environments. A completely edentulous patient received a total of 11 Osseotite implants in the mandible. Six were immediately loaded…

All-On-Four Implant Protocol- Fad or Phenomena Premium Member Content

All-On-Four Implant Protocol- Fad or Phenomena
The All-on-Four protocol uses fewer implants, generally four implants that are placed at mechanical inclinations to maximize support in the fabrication of fixed implant supported prosthetics in fully edentulous patients. The use of angled implant placement allows the clinician to avoid encroachment of anatomic structures such as the sinus, nasal floor or mandibular canal that may make vertical placement difficult or impossible without significant grafting of deficient sites. This webinar will discuss the various treatment options available today for this patient segment and emphasize when and where the All-On-Four protocol can be successfully utilized to eliminate the need for costly augmentation procedures and months of healing time.
