Latar belakang: Stabilitas sekunder memiliki pengaruh besar terhadap oseointegrasi yang pada akhirnya akan mempengaruhi keberhasilan perawatan implan. Desain thread implan merupakan salah satu faktor penting yang mempengaruhi stabilitas implan. Namun belum banyak penelitian yang menganalisa pengaruhnya terhadap stabilitas sekunder. Metode: Penelitian ini merupakan penelitian kuasi eksperimental yang mengevaluasi stabilitas sekunder 44 buah implan dengan jenis implan BL (Bone Level) dan BLT (Bone Level Tapered) masing-masing berjumlah 22 buah implan. Stabilitas implan diukur sebanyak 3 kali pada setiap implan menggunakan alat RFA (Resonance Frequency Analysis). Rerata nilai ISQ (Implant Stability Quotient) akan didapat pada saat pemasangan implan, 1 bulan, dan 2 bulan setelah pemasangan implan. Hasil: Hasil menunjukkan bahwa terdapat perbedaan nilai ISQ yang signifikan antara nilai saat pemasangan implan dibandingkan nilai saat kontrol 1 bulan serta kontrol 2 bulan setelah pemasangan baik pada kelompok BL maupun BLT dengan nilai p < 0,05. Namun, tidak ada perbedaan nilai ISQ yang signifikan antara implan berdiameter 4,1 mm dan 4,8 mm pada jenis implan BL maupun BLT naik pada saat pemasangan implan, saat kontrol 1 bulan, dan kontrol 2 bulan setelah pemasangan dengan nilai p = 0,21. Kesimpulan: Jenis desain thread implan bone level tidak mempengaruhi stabilitas sekunder. Faktor lain seperti diameter implan juga tidak mempengaruhi nilai stabilitas sekunder baik pada jenis implan BL maupun BLT.

Background: Secondary stability greatly influences osseointegration, which ultimately affects the success of implant treatment. Though implant thread design is one important factor influencing implant stability, not many studies have analyzed its impact on secondary stability. Methods: This quasi experimental study involving 44 implants evaluated the biological stability of threaded implants with cylindrical (bone-level; BL) and tapered (bone-level tapered; BLT) designs. Implant stability was evaluated for each implant at 3 time parameters using resonance frequency analysis. A mean implant stability quotient (ISQ) value was calculated for each measurement time. Results: A significant increase in the ISQ value was found at each time parameter consecutively in both implant design groups (P < 0.05). No significant difference was noted in ISQ value between the groups at all 3 time parameters (P = 0.05). There was also no significant difference in the ISQ value at all 3 time parameters between implants with diameters of 4.1 mm and 4.8 mm in the BL and BLT implant groups (P = 0.21). Conclusion: The implant thread designs of BL and BLT implants did not affect the secondary stability. Factors such as implant diameter also did not affect the secondary stability in either implant group.

The first bone cement developed by Charnley in the 1960s using polymethyl methacrylate (PMMA) remains the most widely used material for fixation of orthopaedic joint replacement. In the field of dentistry, polycarbocylate and glass ionomer cements first came to prominence as dental cements in the late 1960s and early 1970s. Although biocompatible, the zinc component results in the formation of a fibrous collagen capsule around the zinc polycarboxylate cement in vivo, which compromises the strength of the intermediate region between the bone and cement. Glass ionomer cements were anticipated to have potential in orthopaedic applications. The discovery of a well integrated intermediate layer between bone and many bioactive ceramic phases from the calcium-phosphate systems, such as hydroxyapatite (HA), resulted in the development of new cements incorporating such phases. Investigations into bioglass and apatite/wollastonite glass-ceramics prompted the development of off-the-shelf bone graft substitute materials. Synthetic hydroxyapatite is commercially available and serves primarily as a scaffold in order to facilitate the bone regeneration process. Many investigations have ranged from the development of castable bioactive materials to modified bioactive composites. This article attempts to give a broad overview of the different types of cements.

Pengembangan material implan gigi anti bakteri berbasis Ti6Al4V termodifikasi dengan TiO2 Nanotube Arrays (TiNTAs) berdopan logam Ag atau Zn, telah dipelajari dalam penelitian ini. Kondisi didalam mulut yang minim energi foton, perlu adanya modifikasi material implan gigi tersebut dengan TiNTAs terdopankan logam (M=Ag; Zn). Kombinasi TiNTAs dengan jenis dan komposisi dopan logam dengan metode Photo Assisted Deposition (PAD) untuk Ag dan in situ untuk Zn dapat berfungsi sebagai electron trapper dan menghasilkan radikal hidroksil sehingga memiliki sifat menghambat pertumbuhan biofilm. Pembuktian sifat menghambat pertumbuhan biofilm dilakukan pengujian uji biofilm static menggunakan model bakteri Streptococcus mutans pada waktu inkubasi 3 dan 16 jam, yang sebelumnya dilakukan terlebih dahulu karakterisasi dengan XRD dan SEM-EDX. Hasil uji sifat menghambat pertumbuhan biofilm yang efektif adalah sampel TiNTAs/G/Ag/0,15, dengan 97,62% disinfeksi bakteri

ABSTRACT
The development of anti-bacterial dental implant material based Ti6Al4V modified with TiO2 nanotube array (TiNTAs) metal doped Ag or Zn, have been studied in this research. Conditions in the mouth minimal photon energy, the need for modification of the dental implant material with TiNTAs metal doped (M = Ag; Zn). TiNTAs combination with the type and composition of metal doped to the method Photo Assisted Deposition (PAD) for Ag and in situ for Zn can serve as electron trapper and produces hydroxyl radicals that have the properties of inhibiting the growth of biofilm. Evidentiary nature of inhibiting the growth of biofilm testing static biofilm test using the model bacterium Streptococcus mutans at 3 and 16 hours of incubation, which previously done first characterization by XRD and SEM-EDX. The result of inhibiting the growth of biofilm properties effective is sampled TiNTAs/ G / Ag / 0.15, with 97.62% disinfection of bacteria

Latar Belakang: Perawatan implan dental sudah berkembang menjadi pilihan yang dapat diterima luas masyarakat. Rumah Sakit Khusus Gigi dan Mulut Fakultas Kedoketran Gigi Universitas Indonesia sudah melaksanakan perawtan implan gigi sejak tahun 2009 dan belum ada evaluasi mengenai implan gigi tersebut. Porphyromonas gingivalis diketahui menjadi salah satu bakteri yang sering digunakan dalam evaluasi jaringan periimplan. Tujuan: Mengevaluasi jaringan periimplan melalui kuantifikasi bakteri Porphyromonas gingivalis. Material dan metode: Dua puluh sembilan sampel implan gigi, lima sampel gigi sehat serta tujuh sampel periodontitis diambil plak subgingiva untuk menghitung Porphyromonas gingivalis melalui Real Time PCR. Hasil: Tidak ada perbedaan bermakna antara kuantitatif P. gingivalis pada sampel periimplan dengan gigi sehat. Terdapat perbedaan bermakna antara kuantitatif P. gingivalis periimplan dengan sampel periodontitis. Kesimpulan: Kuantitatif P.gingivalis gigi sehat menyerupai dengan level kuantitatif pada jaringan periimplan.

ABSTRACT
Background: Dental implants has an excellent results in terms of survival and success rates of oral rehabilitation. Rumah Sakit Khusus Gigi Mulut Fakultas Kedokteran Gigi, Universitas Indonesia (RSKGM FKG UI) is one of leading dental hospital which offer dental implant since 2009 and yet there is no evaluation of dental implant treatment. Aim: The aim of this study was to evaluate periimplant tissue by quantification of bacteria Porphyromonas gingivalis. Materials and Methods: Twenty nine samples periimplant were taken from patient in Periodontal Clinic RSKGM FKG UI. All implants were placed from 2009-2014. Plaque samples were obtained in each dental implant using implant probe. Baseline group was measured in healthy teeth and periodontitis teeth which samples plaque were also taken respectively. All samples were subjected to microbiological analysis using quantification of bacteria Porphyromonas gingivalis with real time PCR. Results: There were no significant differences in number of P. gingivalis between the periimplant groups compared to healthy tooth group (P value >0.05). Meanwhile, there were significant differences between the periimplant group compared to periodontitis teeth (P value < 0.05). Conclusion: Quantification of P.gingivalis in periimplant has a similar result to healthy teeth.
