Introducing The Certain® PREVAIL® Implant: Designed For Preservation of Crestal Bone
By Joseph R. Carpentieri, DDS
INITIAL PATIENT PRESENTATION
A 66-year-old male patient presented with a chief complaint of: “My lower jaw hurts.” The discomfort had been present intermittently for the past 6 months. A periapical radiograph revealed a radiolucency in and around the mesial root of tooth #19 (mandibular left first molar - Figure 1). Periodontal probing around the first molar revealed a purulent and hemorrhagic exudate, pain and discomfort with buccal palpation. Approximately one year prior, the patient had the missing mandibular left second premolar replaced with an OSSEOTITE® Externally Hexed Implant, placed with a twostage protocol. It was restored with a GingiHue® Post and a cement-retained crown.
DIAGNOSIS
- Combined periodontal/endodontic lesion, mandibular left 1st molar (#19)
- Adequate bone volume for implant placement
- Adequate restorative space for fabrication of a single-tooth restoration
TREATMENT PLAN
- Extraction of mandibular left 1st molar, debridement of socket, placement of bone graft/membrane and healing for 8 weeks due to severity of infection (Figure 2)
- Placement of a Certain PREVAIL Implant 5mm(D) x 5.8mm (implant collar) x 13mm(L) with a Full OSSEOTITE Surface in a single-stage surgical protocol; Analog Placement Index (Figure 3) and placement of an Encode® Healing Abutment (Figure 4)
- Fabrication of a master cast using the Analog Placement Index
- 8 weeks unloaded healing, impressions of Encode Healing Abutment and opposing arch
- Scanning, computer design and milling of a Final Encode Abutment for fabrication of a patient specific restoration
- Fabrication of a definitive porcelain fused-to-metal crown for tooth #19
- Placement of definitive restoration
