    Abstract:

    Background: This report is the second part of the previously published study on the impact of light/Chemical Hardening technology and a newly formulated composite graft material for crestal augmentation during immediate implant placement.Methods: A total of 48 implants were placed into the sockets of the mesial roots of freshly extracted mandibular premolar teeth in three minipigs. Crestal areas and intrabony spaces were randomly augmented with light-hardened graft materials including a composite graft consisting of polymethylmethacrylate, polyhydroxylethylmethacrylate, and calcium hydroxide (PPCH) plus polyanhydride (PA); PPCH graft; and PA graft, or left untreated. Distal sockets not receiving implants and the sockets of first molars (n = 60) were randomly treated with one of the graft materials or left empty. In addition, two molar sockets were treated with the original PPCH graft material. Quantitative microcomputed tomography (micro-CT) was used to assess alveolar bone structure and tissue compositio...

  • Immediate Implant Stability and Function: A Minipig Model and Surgical Technique
    Interface Oral Health Science 2011, 2012
    Co-Authors: Hatice Hasturk, Alpdogan Kantarci, Thomas E Van Dyke
    Abstract:

    A successful osseointegrated oral implant is anchored directly to bone, however, in the presence of movement; a soft tissue interface may encapsulate the implant causing its failure. Therefore, immediate implant placement and immediate loading where a primary stability is limited have been considered harmful for a successful osseointegration. The present study was designed as a proof of concept study to evaluate a new technology where the light/Chemical Hardening could enhance the ability of bone substitute material to build an immediate and stable connection with the implant surface at the crestal level and would both increase the primary stability and soft tissue support around the neck of the implant. To test this hypothesis, a newly formulated poly-methyl-methacrylate, poly-hydroxyl-ethyl-methacrylate, and calcium hydroxide plus polyanhydride composite graft material as bone substitute was compared to positive and negative controls in a minipig model. The results of the study demonstrated that the new combination of bone substitute provides better soft tissue and radiographic bone level around immediate implants.

    Abstract:

    Background: The present study is designed as a proof-of-concept study to evaluate light/Chemical Hardening technology and a newly formulated polymethylmethacrylate, polyhydroxyethylmethacrylate, and calcium hydroxide (PPCH) plus polyanhydride (PA) (PPCH-PA) composite graft material as a bone substitute compared to positive and negative controls in a minipig model.Methods: PPCH-PA (composite graft); PPCH alone (positive control), PA alone (positive control), and no graft (negative control) were compared. Four mandibular premolar teeth per quadrant were extracted; a total of 48 implants were placed into sockets in three minipigs. Abutments were placed protruding into the oral cavity 4 mm in height for immediate loading. Crestal areas and intrabony spaces were filled with PPCH-PA, PPCH, or PA using a three-phase delivery system in which all graft materials were hardened by a light cure. In the negative control group, implant sites were left untreated. At 12 weeks, block sections containing implants were obta...
