目的: 支台築造の術式および材料についての実状を把握する目的で, 1977, 1986, 1993年の調査に引き続き2001年に実態調査を行い, 過去3回の調査結果と比較検討した.<BR>方法: 調査対象は, 2001年2~4月までの間に鶴見大学歯学部附属病院補綴科診療室において支台築造を施されたすべての支台歯と支台築造とした. 調査項目は患者, 支台歯, 支台築造のデータの各項目とした.<BR>結果: 患者総数225名, 支台歯総数311歯が対象で, 生活歯が5%, 失活歯が95%であった. また, 歯質の残存状態では, 残存歯質量が少ないと推察される支台歯が少なくなかった. 支台築造は61%でレジン支台築造が, 39%で鋳造支台築造が選択されていた. レジン支台築造は70%が間接法で, 30%が直接法で行われていた. 鋳造支台築造の合着用セメントは71%で接着性レジンセメントが選択されていた. 鋳造支台築造の築造体は83%で装着前にサンドブラスト処理が行われ, 接着性レジンセメントを使用する場合, 97%で金属接着性プライマーが併用されていた.<BR>結論: 過去3回の調査と比較すると, 今回の調査結果では接着性材料が選択された頻度は高く, 信頼性が高まった象牙質接着を使用して脱落や歯根破折に対する対策を積極的に講じていることがわかった.

Purpose: A survey was performed in 2001 in order to grasp the actual condition regarding methods and materials of foundation restorations. The results of 3 surveys in 1977, 1986, and 1993 were compared.<BR>Materials and Methods: All abutment teeth and core buildup that were treated by foundation restoration at Tsurumi University Dental Clinic Prosthodontics Treatment Room were set as the survey target from February to April 2001. The survey items were patients, abutment teeth, and data of core buildup.<BR>Results: Core buildups of 311 teeth of 225 patients were examined. In all abutment teeth, there were 5% of vital teeth and 95% of non-vital teeth. There were many abutment teeth with little remaining tooth structure. Regarding type of core buildup, cast metal core buildups were chosen by 61% and composite resin core buildups were chosen by 39%. In composite resin core buildups, the indirect method was performed in 70% and the direct method was performed in 30%. As for luting cement, adhesive resin cement was chosen by 71% at the time of cast metal core buildup. Sand blast process ing was performed before setting in 83% at the time of cast metal core buildup. And at the time of use, 97% used an adhesive metal primer for the adhesive resin cement.<BR>Conclusions: Compared with the results of the 3 previous reports, this survey showed that many composite resin core buildups and adhesive resin cement of adhesive material were chosen. Reliable dentin adhesion can be used for dislodgement or root fracture.
