The document discusses post-core-crown restorations. It provides a historical background and summarizes key findings from studies on post length, diameter, form and failure rates. Threaded posts have the highest retention but also highest risk of root fracture. Parallel-sided posts have less retention but distribute stresses more evenly. At least 4mm of gutta-percha should remain at the apex. Post length is generally recommended to be 3/4 of the root length. Proper post diameter is 1/3 the root width or less.

1) Vertical root fractures are longitudinal fractures in tooth roots that can be difficult to diagnose.
2) Diagnosis involves examining clinical signs like pain, sinus tracts, and isolated periodontal pockets as well as performing diagnostic tests including dye tests, vitality tests, transillumination, and various types of radiographs.
3) Early diagnosis is important to prevent extensive bone loss, which makes future treatments like implants more complicated.
This document provides diagnostic terminology recommended by the AAE Consensus Conference for pulpal and apical conditions. It defines normal pulp and various stages of reversible and irreversible pulpitis, as well as pulp necrosis. For apical conditions, it defines normal apical tissues and various inflammatory conditions including symptomatic and asymptomatic apical periodontitis, acute and chronic apical abscesses, and condensing osteitis. The terminology is intended to standardize descriptions of pulpal and apical diagnoses.
This document outlines the laboratory procedures for fabricating a removable partial denture framework.

1. An endodontically treated tooth can function well if restored properly, but special techniques are needed due to loss of tooth structure from previous treatments.
2. Factors such as root length, tooth anatomy, amount of remaining coronal structure, and stress factors must be considered when selecting a post and core system.
3. Post options include custom cast posts or prefabricated posts made of metal, fiber-reinforced composite, carbon fiber, or zirconia. Core materials include cast cores or direct cores made of amalgam, composite, or glass ionomer cement.
The wax pattern is a precursor to the final cast restoration and must be fabricated precisely. There are two techniques for making wax patterns - direct and indirect. Various waxes are used depending on the type of restoration. For inlay patterns, the wax needs to flow easily when heated but be rigid when cool and carve precisely without distortion. The pattern is stored on the die and invested soon after fabrication. The die is prepared, relieved, and lubricated before pattern fabrication. Patterns are built up by adding wax for the coping, axial contours, emergence profile, occlusal morphology, and refined margins. Cusp-marginal ridge and cusp-fossa occlusal schemes are classified.
The document discusses various aspects of clasp design for removable partial dentures. It begins by defining what a clasp is and describing different clasp classifications such as occlusally approaching and gingivally approaching clasps. It then examines specific clasp designs like circumferential, bar/Roach type, and combination clasps. The document outlines the functional requirements of clasps, including retention, support, stability, and reciprocation. It also reviews several statements about clasp design, discussing whether prosthodontic experts agree or disagree with them based on clinical factors.

This document discusses dental veneers, which are thin shells made of tooth-colored materials that are bonded to the front of teeth. There are two main types of veneers: composite veneers, which can be applied directly in the dental office, and porcelain veneers, which require two appointments and are fabricated outside of the mouth in a dental lab. Veneers can improve esthetics by correcting crooked, stained, chipped, or misshapen teeth. They involve a minor preparation of the tooth surface and are bonded securely. Veneers provide a conservative and durable way to enhance the appearance of the smile.

The matrix is used to restore the anatomical shape and proximal contacts of a tooth during a restoration. It consists of a matrix band and retainer. For amalgam, the Tofflemire matrix or AutoMatrix are commonly used, while for composites, plastic strip, shell, or sectional matrices are used. Wedges are used to secure the matrix band in place and prevent overhangs of filling material. Different matrix types and retainers are selected based on the material and type of restoration being performed.
This document discusses different techniques for fabricating collarless metal-ceramic restorations with porcelain shoulders. It describes the platinum foil matrix technique, direct lift (cyanoacrylate resin) technique, and porcelain wax technique. The platinum foil technique uses a platinum matrix welded to the framework to support the porcelain during firing. The direct lift technique applies cyanoacrylate resin to the die and builds porcelain directly onto it. The porcelain wax technique uses a mixture of body porcelain and wax applied to the die for final adaptation of the porcelain margin. All three techniques aim to provide esthetic porcelain margins without compromising marginal fit or strength.

2. PENDAHULUAN
Tujuan utama layanan prosthetik adalah untuk mengembalikan fungsi
normal pada pasien secepat mungkin.
Konsep dasar overdenture adalah untuk memelihara jaringan lunak dan
keras yang tersisa.
3. DESAIN PROSTETIK DASAR
Penyebab kegagalan
gigitiruan tidak dapat diatasi
dengan fiksasi attachment
Penggunaan attachment
tidak dapat meninggalkan
prinsip-prinsip dasar
Kegagalan gigitiruan hibrid
terjadi bukan karena
attachment
tetapi karena seleksi
attachment yang tidak sesuai
kegagalan dokter gigi untuk
mengembangkan ekstensi
basis maksimum gigitiruan,
segel atmosferik, dan untuk
basis mandibula, menutupi
retromolar pad.
Catatan oklusal yang tidak
sesuai menyebabkan
kerusakan pada sedikit gigi
yang tersisa.
4. DESAIN PROSTETIK DASAR
Penggunaan attachment memperkenalkan faktor lain dalam rancangan
prostetik dasar, yaitu : persyaratan untuk hubungan prostesis-
attachment yang tepat
Untuk setiap tipe attachment, persyaratannya berbeda, bergantung
kepada ketersediaan atau daya pegas yang diinginkan dan adaptasi
keseluruhan dari basis gigitiruan di atas jaringan keras dan lunak pada
daerah beban gigitiruan
5. KEBERHASILAN PENGGUNAAN
OVERDENTURE
Pasien adalah manusia yang memiliki emosi
dan harus dievaluasi secara medis dan dental
Keinginan dan pengetahuan dental pasien
harus dipertimbangkan

semen cetakan koping. C, Koping Dowel dengan attachment. D, restorasi komposit atau
aloy dengan dudukan orientasi untuk overdenture. E, Preparasi minimal, dirawat secara
endodontik, dilingkari, direstorasi dengan komposit atau aloy.
9. Salah satu penyebab kegagalan dari post preparasi koping yang membawa
attachment adalah kurangnya dinding pada interfase post- koping-
attachment (kanan). Hal ini menyebabkan fraktur atau bukaan dari koping.
Gambar sebelah kiri menggambarkan dudukan inlay yang sesuai yang
memposisikan koping, mencegah rotasi, dan menyediakan dinding yang
sesuai (Dimodifikasi dari Gerber, A., 1964)
10. Koping Dowel harus memberikan tonjolan gingiva secara
gradual untuk melindungi marginal gingiva.
A, Jika teknik mahkota ganda diterapkan, kuncian alur kecil
dicetakkan di atas akar sebagai kunci koping sekunder. B,
Koping sekunder dapat membawa attachment batang dan
dapat dikunci pada koping dowel dengan sistem sekrup.
11. TEHNIK MENCETAK
Tehnik mencetak dan
materi yang digunakan
beragam menurut
pilihan personal.
Materi elastomerik
sama baiknya seperti
cetakan individual
compound
Mencetak dowel lebih
rumit karena adanya
jalur divergen
Direkomendasikan
beberapa tehnik
mencetak
1. Koping dowel dibuat,
cetakan master
sekunder
2. Cetakan individual
dan cetakan full pada
gigi preparasi,
menggabungkan dowel
pada koping dengan
resin.
12. Prosedur laboratorium
Koping dibuat dengan malam pada ketebalan oklusal
minimal 1 mm
Permukaan oklusal koping dimodifikasi untuk menerima
tipe attachment yang digunakan
Attachment disolder pada koping setelah dicetak .
Orientasi didapatkan dengan sebuah paralelometer
Secara umum orientasi attachment dalam hubungannya
dengan koping ditunjukkan oleh posisi resin gigi dan
jarak bukolingual dan oklusogingiva yang tersedia.
13. RANCANGAN DOWEL
CETAKAN DOWEL : Ekspansi alloy
penting untuk mempertimbangkan
apakah dowel dan koping dibuat
dari malam bersama dan casting
sebagai satu unit
Pertimbangan lainnya dalam
menggunakan tipe dowel ini adalah
bahwa biasanya memilki dinding
lebih besar dalam diameter untuk
menerima kekuatan yang ekuivalen
dari dowel logam sebelum fabrikasi
POLA SEBELUM FEBRIKASI
RESIN : bur yang sesuai untuk
mempreparasi jarak dowel. Cetakan
dowel kurang dari panjang 6 mm
dan taper tidak membantu
dukungan terhadap koping-
attachment, dan dudukan yang tidak
sempurna serta fraktur akar dapat
terjadi selama sementasi
PREFABRIKASI DOWEL METAL :
Lebih memiliki keuntungan karena
kesesuaian yg tepat, membutuhkan
pembesaran yang minimal,
memperkuat gigi bukan
melemahkan.
DOWEL ULIR : memberikan fiksasi
mekanis sebagai tambahan terhadap
sementasi. Keuntungan membantu
sementasi dan kerugiannya gigi
dapat fraktur.
14. SISTEM DOWEL
Sistem dowel pasak step Schenker memiliki dua konfigurasi,
satu untuk saluran akar yang kecil dan satu untuk yang besar.
Step berakibat pata akar taper dan dinding paralel
memberikan retensi maksimal pada saluran akar.
screw VK dan Kurer menyediakan ikatan mekanik yang rigid
pada koping. Koping dapat di wax secara langsung pada inti
screw(gbr 15-10). Fiksasi screw adalah self-taping
Sekrup VK terdiri dari sekrup self-taping ganda dan tube ulir
yang lebih besar untuk menambah diameter saluran yang
lebih besar. Gbr. 15-11. Sekrup ganda dapat digunakan untuk
fixed removable bridge work dan sebagai basis untuk
attachment superstruktur.

lebih dari 20 tahun dengan lebih
dari 800 pasien yang telah
memiliki gigitiruan fiksasi bar
yang sukses
16. Attachment
Bar dibandingkan dengan fiksasi stud
jika basis gigitiruan sudah
dibuat baik sedemikian
rupa sehingga bar hanya
sebagai alat fiksasi, apakah
ada perbedaan dengan hasil
splinting yang didapatkan
dalam prostesis stud dan
prostesis bar.
Pemisahan dua
atau lebih gigi
dengan sebuah bar
menghasilkan
stabilitas yang
sama dengan
attachment tipe
stud rigid jika
overdenture
ditempatkan
Secara teori, tidak terdapat
perbedaan, tetapi tipe stud
membantu pergerakan bebas, dan,
jika satu gigi lemah, gigi yang kuat
dapat menjadi poin fulcrum untuk
pergerakan gigi yang lebih lemah
pada prostesis.
SEDERHANA
18. Attachment stud
(kancing tindis)
Sebagian besar
attachment tipe-stud
dapat dianggap sebagai
pengunci stud dan
paling sederhana dalam
konsep,
Beberapa attachment
stud, seperti Gerber,
adalah berpegas dan
memiliki pegas-balik; di
mana yang lainnya seperti
silinder Dalbo, dalah
pegas jaringan, dan yang
lainnya juga seperti
Introfix, adalah tidak
berpegas.
Attachment berpegas
dapat menjadi
unidireksional atau
multidireksional dan
melibatkan gigi kedua
baik attachment bar
maupun teleskop stud.
Sebuah faktor
kompensasi pada
attachment berpegas
membantu basis gigitirun
untuk didukung
sepenuhnya oleh jaringan
dalam fungsi daripada
oleh gigi.
19. STUD BERPEGAS
Sistem attachment berpegas
diseleksi untuk menunjukkan
layanan kompensasi dan bertindak
sebagai katup pengaman untuk
setiap situasi muatan berlebih
Tidak boleh dua sistem attachment
berpegas saling berlawanan satu
dengan yang lainnya
Kecuali attachment pada prostesis
maksila tidak dapat berfungsi,
untuk prostesis maksila menerima
dukungan tambahan dari cakupan
palatal.
Gigi dengan attachment
memberikan retensi dan posisi atau
orientasi arah untuk perangkat.
Ketidakmampuan untuk
mengembangkan basis gigitiruan
untuk dudukan yang baik,
attachment berpegas baik bagi
penerimaan prostesis dengan
membantu memberikan kontak
basis yang lebih banyak dan
dukungan saat berfungsi.
20. Stud non-pegas
Attachmentan stud nonpegas digunakanan jika jarak interoklusal
terbatas. Mereka harus digunakan jika gigi stabil atau jika dokter
gigi tidak membutuhkan pergerakan atau potensi pergerakan dari
overdenture
