CLINICAL MANUAL
ROOT KEEPER TYPE MAGNETIC ATTACHMENT
Following root canal treatment of the abutmen tooth, the Root Keeper type Magteeth magnet
attachment can be conducted
I. PREPARATION OF ABUTMENT TOOTH
1. Protection of gingiva by retraction cord
2. Removal of softened dentin by turbine and diamond point, contra and round bar. Use caries
detection solution
3. Formation by peeso reamer and root crown forming bur
4. The root preparation depth should be (root keeper post length) +1-2 mm, marked with a
rubber stop
5. Form a tapering at the upper part of the root canal if necessary
II. TRIAL FITTING OF ROOT KEEPER
1. Fix the root keeper to the tooth restoration with adhesive stick and fit it to the abutment
tooth
2. Check the positional relationship between the upper edge of the abutment tooth and the
base of the root keeper (visually)
III. SURFACE TREATMEN OF ROOT KEEPER AND MAGNETIC STRUCTURE
1. Sandblasting (alumina 50 mikro m and 0,3 MPa, 3 seconds)
Protect MA-RK joint surface (both root keeper and magnet structure are protected with
tape)
2. Application of metal primer
IV. FIXATION OF ROOT KEEPER TO ABUTMENT TOOTH
1. Ecthing treatment in the root canal and prepared abutment tooth surface
2. Rinsing and drying (air)
3. Apply bonding agent
4. Visible light cure polymerization
5. Protect the root keeper bonding surface with celluloid strip, trimmed to a slightly wider than
root keeper diameter
6. Apply core buildup resin to the prepared root canal and on the corner between RK and
celluloid strip interface
7. Root keeper is placed in the cavity using adhesive stick parallel to the occlusal plane
8. Remove excess resin to the extent possible using a probe or other instrument9. Visible light cure polymerization
V. ROOT CAP RESIN TRIMMING
1. Adjusting the root cap shape
(Super fine diamond point, high speed handpiece (Contra and silicone point) Compomaster)
2. Removal of celluloid strip
VI. DENTURE USE (WITHOUT MAGNET ASSEMBLY)
1. The denture will be used without magnetic structure for about one month (explanation only)
2. Check with white silicone (fit checker) that there is enough space between the keeper and
the denture (to prevent damage to the upper surface of the keeper)
VII. PLACEMENT OF MAGNET STRUCTURE
1. Use a round bar to hollow out the area on the inner surface of the denture where the
magnet structure is to be placed
2. Place the magnetic structure on the keeper and check if there is enough clearance with
white silicone (fit checker)
3. Place the tongue channel (toward the lingual side) (small round bar)
4. Apply immediate curing resin monomer to the bonding surface of the denture (also lightly
on the magnet structure)
5. Apply Vaseline to the abutment teeth (if there is undercut, more to block out)
6. Place self-curing resin on the prepared inner surface of the denture
7. Attach the denture to the model (prepare the upper denture for bitting)
8. Confirm that the resin comes out from the spillway
9. Confirm resin polymerization by palpating the resin on the spillway
10. Remove the denture
VIII. DENTURE SHAPE CORRECTION AND POLISHING
1. Trimming the denture inner surface (resin that has entered the gingival sulcus)
2. Trimming of the resin in the tonsillar canal
3. Polishing
IX. CONFIRMATION
Remove the denture and confirm if the magnetic force is effective
CARA PAKAI
Setelah perawatan saluran akar gigi abutment, pemasangan magnet Magteeth tipe Root Keeper dapat
dilakukan
I. PERSIAPAN GIGI ABUTMENT
1. Proteksi gingiva dengan retraction cord
2. Hilangkan bagian dentin yang melunak dengan handpiece dan diamond point, contra dan
round bur/tungsten carbide bur. Gunakan larutan indikator karies
3. Preparasi saluran akar dengan Peeso reamer dan bur pembentuk mahkota akar
4. Kedalaman preparasi saluran akar sebanyak (panjang tiang root keeper) + 1-2 mm, ditandai
dengan rubber stop
5. Bentuk bevel di bagian atas saluran akar jika perlu
II. UJI COBA PEMASANGAN ROOT KEEPER
1. Masukkan root keeper dengan tangkai perekat dan pasangkan ke gigi abutment
2. Periksa posisi antara permukaan atas gigi penyangga dan dasar root keeper (secara visual)
III. SURFACE CONDITIONING SALURAN AKAR DAN ROOT KEEPER
1. Sandblasting (AlO2 50 µm, 0,3 MPa, 3 detik)
Lindungi permukaan kontak MA-RK (root keeper dan magnet assembly dilindungi dengan
selotip)
2. Aplikasi metal primer
IV. PEMASANGAN ROOT KEEPER PADA GIGI PENYANGGA
1. Etsa permukaan saluran akar dan permukaan gigi abutment yang telah dipreparasi
2. Bilas dengan air dan keringkan (udara)
3. Aplikasi bonding
4. Polimerisasi (light cure)
5. Lindungi permukaan kontak RK-MA dengan strip seluloid, dipangkas sedikit lebih lebar dari
diameter penjaga akar
6. Oleskan core build-up resin ke saluran akar yang telah disiapkan dan di sudut antara RK dan
strip seluloid
7. Insersi root keeper ke dalam saluran akar menggunakan tangkai perekat yang sejajar dengan
bidang oklusal
8. Hilangkan kelebihan resin menggunakan probe atau instrumen lain
9. Polimerisasi (light cure)V. FINISHING RESIN ROOT CAP
1. Menyesuaikan bentuk root cap
(Diamond point super-fine, high-speed handpiece dan silicone point)
2. Lepas seluloid strip
VI. PENGGUNAAN GIGI TIRUAN (TANPA MAGNET ASSEMBLY)
1. Gigi tiruan akan digunakan tanpa magnet assembly selama satu bulan (hanya penjelasan)
2. Periksa dengan denture fitness checker apakah ada ruang yang cukup antara keeper dan gigi
tiruan (untuk mencegah kerusakan pada permukaan atas keeper)
VII. PENEMPATAN MAGNET ASSEMBLY
1. Gunakan round bur untuk melubangi area pada permukaan bagian dalam gigi tiruan di mana
magnet assembly akan ditempatkan
2. Tempatkan struktur magnet pada keeper dan periksa apakah ada jarak yang cukup dengan
denture fitness checker.
3. Buat spillway (ke arah sisi lingual) (round bur kecil)
4. Oleskan monomer resin langsung ke permukaan bonding gigi tiruan (oleskan juga secara tipis
pada magnet assembly)
5. Oleskan Vaseline pada abutment (jika ada undercut, aplikasikan lebih banyak block out)
6. Tempatkan resin self-curing pada permukaan bagian dalam gigi tiruan yang telah disiapkan
7. Pasang gigi tiruan
8. Pastikan bahwa resin keluar dari spillway
9. Pastikan polimerisasi resin dengan meraba resin pada spillway
10. Lepaskan gigi tiruan
VIII. FINISHING & POLISHING GIGI TIRUAN
1. Finishing permukaan bagian dalam gigi tiruan (resin yang masuk ke dalam sulkus gingiva)
2. Finishing resin di spillway
3. Polishing
IX. KONFIRMASI
Lepaskan gigi tiruan dan pastikan apakah gaya magnet bekerja dengan baik
