The use of BioHPP (high performance polymer) as superstructure material in oral implantology
Bibliographic record
Abstract
Background The modify poli-ether-ketone has been used as an alternative material for manufacturing the superstructure prosthesis over the dental implants. In our study we have analyzed the fixed overdentures of 21 patients. The overdenture is fixed on dental implants placed by all-on-4 and all-on-6 protocols. A retrospective study of edentulous patient on Albanian University was performed from September 2016 – March 2018. Aim/Hypothesis The aim of this study was to find alternative materials that has such properties that help us to improve the quality of our prosthetic work, helping our patients to leave from the dental clinic with a definitive prosthesis within the first 24 hours. Material and Methods 168 implants (108 implants in maxilla and 60 implants in the mandibula) were placed at 21 edentulous patients due to all-on-4 and all-on-6 protocols. The group was divided in 4 previously edentulous patient and 17 post extractive ones and immediate implantation patients. The fixed prosthetic Toronto bridge in BioHPP was delivered in the first 24 hours. The patients were followed up for one and a half year. Results All the patients were followed up for 18 months. The first control was 2–3 days after the surgery, 7 days after we invite them for the removal of the suture (usually resorbable sutures were used but sometimes parts of them were founded to be removed). The disassembly of the fixed prosthesis for the first time was after 6 months for the maxillary and after 3 months for the mandibula. The dynamometer control of the abutments and connection screws was affectuated. The follow-up for the hygiene was any 3- 4 months on the first year. The new home oral hygiene techniques- super floss, waterpik, etc. for a better hygiene were explained to the patient. We had no implants loosed, no allergic reaction. We had to rebase 5 fixed prosthesis, 4 prostheses from the maxilla and 1 prosthesis of the mandibula. The 5 of them were from the group of post extractive implant placement. Conclusions and Clinical Implications BioHPP fulfills prothesist's expectations giving a permanent fixed prosthesis in the first 24 hours from the surgery. In edentulous patients it is an ideal solution as they get their definitive prosthesis fixed in 24 hours, while with other types of techniques or resins they get provisional ones in 24 hours which are replaced later on by definitive prosthesis. Only the post-extractive cases has to be rebased with resin at the time of complete osseointegration.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
