Cumulative survival rate of Astra Tech implants: a retrospective analysis

Abstract

PurposeThe aim of this study was to analyze the short-term predictability and reliability of Astra Tech implants according to the demographical distribution of patients and condition of implant sites and location of implants.MethodsAmong patients treated with Astra Tech implant (Astra Tech AB) in the Department of Periodontology at the Dental Hospital of Yonsei University of College of Dentisry and K Dental Clinic from May 2004 to March 2009, 195 implants in 98 patients which had been restored more than 6 months ago were reviewed in this study. Following data were reviewed from patient charts and implants success rate was examined: 1) patient type and implant location, 2) bone status at the implant site, 3) diameter and length of the placed implants, 4) presence or absence of bone augmentation and types of the augmentation.ResultsThe results from this study are as follows: 1) most implants were placed in the molar area, especially 1st molar area of maxilla, 2) most implants were placed at D2 and D3 bone type, 3) most implants were placed in areas of B and C bone quantity, 4) autogenous and alloplastic bone graft and artificial membrane were used for placement of 74 implants.ConclusionsShort-term survival rate of Astra Tech implants was 100%.

Usage of Bone Replacement Grafts in Periodontics and Oral Implantology and Their Current Levels of Clinical Evidence — A Systematic Assessment

“…Overall, 55 studies were categorized at level I 12–66 . Twenty‐six were level II, 67–92 nine were level III, 93–101 46 were level IV S1‐S46 (see references in http://www.joponline.org/doi/suppl/10.1902/jop.2016.150512/suppl_file/150512_supapp1.pdf and http://www.joponline.org/doi/suppl/10.1902/jop.2016.150512/suppl_file/150512_supapp2.pdf in online Journal of Periodontology ), and 53 were level V S47‐S99 (see references in http://www.joponline.org/doi/suppl/10.1902/jop.2016.150512/suppl_file/150512_supapp1.pdf and http://www.joponline.org/doi/suppl/10.1902/jop.2016.150512/suppl_file/150512_supapp3.pdf in online Journal of Periodontology ). The levels of evidence of each type of bone graft and summary of the RCTs are presented in http://www.joponline.org/doi/suppl/10.1902/jop.2016.150512 in online Journal of Periodontology .…”

“…These level I studies are summarized in http://www.joponline.org/doi/suppl/10.1902/jop.2016.150512/suppl_file/150512_suptab2.pdf in online Journal of Periodontology . There were eight studies 70,79,81‐86 and five studies 94,97‐100 that met level II and III criteria, respectively. The majority were level IV studies (21 studies) S1‐S21 (see references in http://www.joponline.org/doi/suppl/10.1902/jop.2016.150512/suppl_file/150512_supapp2.pdf in online Journal of Periodontology ).…”

“…There were more level I studies involving alloplasts when compared with allografts and xenografts (26 studies) 17‐24,26,28,51‐66 . Levels II and III represent eight studies 69‐72,77,90‐92 and four studies, 93‐95,101 respectively. These Type I studies are summarized in http://www.joponline.org/doi/suppl/10.1902/jop.2016.150512/suppl_file/150512_suptab6.pdf in online Journal of Periodontology .…”

Dental İmplant Uygulamalarinin Demografi̇k Ve Kli̇ni̇k Özelli̇kleri̇ni̇n Değerlendi̇ri̇lmesi̇

“…8 Hastaların dişsizlik durumu incelendiğinde; en sık görülen durumun dişsiz sonlanan kısmi dişsizlik (32 adet (%37)) olması, çalışmanın yaş aralığının geniş ve ortalama yaşın benzer çalışmalara göre düşük olması ile ilişkilendirilebilir. 11,12 Ayrıca tek diş eksikliği durumunun (26 adet (%30) ve dişli sonlanan kısmi dişsizlik (21 adet (%24)) klinik tablolarının da oldukça sık olduğu görülmüştür. Bu durum hastaların retansiyon ihtiyacından daha çok estetik ve komşu doğal dişlerin korunması hedefleri ile dental implant tedavisini talep ettiklerini gösteren bir bulgu olarak düşünülebil-mektedir.…”
