DENTAL IMPLANTS-1 HISTORY- Dr MEENU MERRY C PAULMeenuMerryCPaul
Dental implants are artificial titanium fixtures surgically placed into the jawbone to replace missing teeth and their roots. Pioneered by Per-Ingvar Branemark in the 1950s, who discovered that titanium forms a biological bond with bone called osseointegration. Since then, titanium has become the material of choice for dental implants. Implants can replace single teeth, multiple teeth, or serve as anchors for dentures, offering improved function, aesthetics, and oral health compared to other tooth replacement options.

Commonly used antibiotics like tetracycline, doxycycline, metronidazole, penicillin, and amoxicillin-clavulanate are described in detail. The document concludes with a reference to research on systemic antibiotic use in periodontics.
This document discusses evidence-based periodontology and decision making. It defines evidence-based periodontology as applying evidence-based healthcare to periodontology by integrating the best available evidence with clinical practice. The document outlines the steps of evidence-based periodontology, including asking questions using the PICO format, searching for and appraising evidence from systematic reviews and clinical practice guidelines, and applying the evidence to clinical decisions. It also discusses tools for critically assessing evidence, such as considering different levels of evidence and ensuring temporality between causes and effects.
Calcium and Phosphorous metabolism 23-03-23.pptxmalti19
Calcium and phosphorus metabolism is tightly regulated by vitamin D, parathyroid hormone, and calcitonin. Calcium is crucial for bone development, nerve function, and other processes. The recommended daily intake is 800 mg for adults. Dietary sources include dairy products, leafy greens, and fish. Absorption occurs in the small intestine and is influenced by vitamin D, PTH, and other factors. Hormonal signals work to maintain calcium levels within a narrow range. Disorders like rickets and osteomalacia can result from vitamin D deficiency. Precise regulation is needed to prevent hypercalcemia or hypocalcemia.
The document summarizes the anatomy and function of the muscles of mastication. It describes the three main muscles - masseter, temporalis, and medial and lateral pterygoid. It discusses their embryological development, nerve supply, actions, and clinical evaluation. The masseter muscle is palpated to assess for hypertrophy. Orthodontic treatment can impact the thickness of the muscles. The medial pterygoid muscle is also described in more detail, including its nerve supply by the mandibular nerve, blood supply, actions, and clinical examination.
The facial nerve emerges from the brainstem between the pons and medulla. It has motor, sensory, and parasympathetic secretomotor components. During embryonic development, it arises from the second branchial arch. The nerve passes through the internal acoustic meatus and facial canal within the temporal bone. It gives off several branches within the facial canal before exiting at the stylomastoid foramen. Its main branches in the face include the temporal, zygomatic, buccal, marginal mandibular, and cervical branches which innervate the muscles of facial expression.
1) PRP and PRF are platelet concentrates that provide growth factors that may enhance tissue regeneration.
2) Studies have shown PRP and PRF can increase the release of growth factors like PDGF, TGF-β1, and VEGF compared to control groups.
3) However, the evidence on whether PRP and PRF improve bone regeneration outcomes is mixed. Some studies found benefits for parameters like new bone formation and defect fill, while other studies found no additional benefits compared to control treatments.
This document discusses chlorhexidine, a commonly used chemical plaque control agent. It provides details on the history, chemistry, forms, mechanisms of action, products, clinical uses, toxicity and side effects of chlorhexidine. Chlorhexidine is a bisbiguanide antiseptic that is highly effective at inhibiting plaque formation and controlling gingivitis when used as a mouthrinse. It has a wide range of clinical applications and is generally well-tolerated, though long-term use can cause staining and changes to taste sensation in some individuals.
Oral hygiene and overall health
Department of Periodontology and oral Implantology
The document discusses the importance of oral hygiene for preventing dental diseases and maintaining overall health. It notes that over 3.5 billion people suffer from oral diseases according to the WHO, but many can be prevented through proper oral hygiene. Maintaining oral hygiene includes brushing teeth twice daily, flossing, cleaning the tongue, and visiting the dentist regularly. Poor oral hygiene can lead to dental caries, gum disease, and systemic issues like diabetes and heart disease.
Reducing fracture risk with Calcium and Vitamin D
Osteoporotic fractures are a major health problem that most commonly affect the spine and hip. Low calcium intake and vitamin D deficiency increase fracture risk by reducing bone mineral density and strength. Clinical trials show that calcium and vitamin D supplementation can reduce fracture risk, especially when vitamin D doses reach 800 IU daily and calcium intake reaches 1000-1200 mg. For older individuals, supplementation is most effective for those at high risk of deficiency living in nursing homes or with low dairy intake.
Antibiotics in the management of chronic periodontitis.pptmalti19
This document summarizes evidence on the use of adjunctive antibiotics for chronic periodontitis. A systematic review of 25 studies found some additional benefits of antibiotics in deep pockets, including 0.2-0.6 mm more attachment gain and 0.2-0.8 mm more probing depth reduction. However, the clinical relevance is uncertain given limitations in defining chronic periodontitis and its microbiota. Overall, current studies have not conclusively established benefits of adjunctive antibiotics, so they cannot be routinely indicated as adjuncts for chronic periodontitis.
The document discusses immediate dentures, which are complete or partial dentures fabricated immediately after tooth extraction. It describes the differences between conventional (classic) immediate dentures and interim (transitional) immediate dentures. Conventional immediate dentures are intended as the long-term prosthesis and are made when only anterior teeth remain. Interim immediate dentures are short-term and are made when posterior teeth remain, requiring only one surgical visit. The document outlines the procedures, indications, contraindications, advantages and disadvantages of both types of immediate dentures.
This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.
A Visual Guide to 1 Samuel | A Tale of Two HeartsSteve Thomason
These slides walk through the story of 1 Samuel. Samuel is the last judge of Israel. The people reject God and want a king. Saul is anointed as the first king, but he is not a good king. David, the shepherd boy is anointed and Saul is envious of him. David shows honor while Saul continues to self destruct.
Temple of Asclepius in Thrace. Excavation resultsKrassimira Luka
The temple and the sanctuary around were dedicated to Asklepios Zmidrenus. This name has been known since 1875 when an inscription dedicated to him was discovered in Rome. The inscription is dated in 227 AD and was left by soldiers originating from the city of Philippopolis (modern Plovdiv).

orient the implant to the occlusal plane to
facilitate prosthetic therapy.
oDifferent abutments are available for different
prosthetic applications
oImplant position and angulation may require
different abutments to allow optimum esthetics.

protocols and materials that further expand
their use in the fixed replacement of natural
teeth.
oThis has contributed in part to the evolution of
“restoration-driven” implant dentistry.
97. Terminologies
oAbutment /abut·ment/ a supporting structure to
sustain lateral or horizontal pressure, as the anchorage
tooth for a fixed or removable partial denture.
Dorland's Medical Dictionary for
Health Consumers
oAbutment : that part of a structure that directly receives
thrust or pressure; an anchorage : a tooth, a portion of a
tooth, or that portion of a dental implant that serves to
support and/or retain a prosthesis usage.
GPT 8
98. oAbutment analog : a replica of the superior portion of
a dental implant. Usually used to provide an exact form of
the dental implant abutment within the dental laboratory
during fabrication of a prosthesis supported in part or
whole by the dental implant
oAbutment clamp ;any device used for positioning a
dental implant abutment upon the dental implant body
oAbutment driver : any hand instrument usually
specifically made to assist in insertion and securing of a
dental implant abutment to the superior portion of a
dental implant
GPT 8
99. oAbutment healing cap : any temporary cover used to
provide a seal over the superior portion of a dental implant;
most such covers are metallic and are intended for interim
usage following exposure of the dental implants superior
surface
oAbutment post : that component of a dental implant
abutment which extends into the internal structure of a dental
implant and is used to provide retention and/or stability to the
dental implant abutment
oAbutment screw : that component which secures the dental
implant abutment to the dental implant body
GPT 8
100. Implant components:
oTo understand the characteristics and function of
an implant, one must have knowledge of its
component parts. Although each implant system
varies the parts are basically consistence .
oThe system that pioneered clinical prosthodontic
applications with the use of commercially pure
titanium endosseous implants is that of
branemark and co-workers.
101. The component parts are:
1.Implant fixture

103. Implant Fixture:
oFixture is the component placed with in the bone
during the first stage surgery. It may or may not be
threaded and is normally made of titanium or titanium
alloy of varying roughnesses.
oAn implant provides the anchor or foundation for a
restoration. It is screwed into the bone of the jaw
providing a fixed platform on which an abutment can
be screwed.
oAll contemporary dental implants have an internally
threaded portion that can accept second stage screw
placements.
o These implants also may incorporate an
antirotational feature within the implant body which
may be internal or external.
104. Implant Fixture:
oDepending on the implant system, the fixture can
have different surfaces-threaded, grooved,
perforated, plasma sprayed or coated.
o Each surface type is meant for a particular
purpose such as increase surface area
enhances osseointegration or better cortex
engagement ensures immediate and long term
bone anchorage.

105. Cover screw
oThe cover screw acts as a seal on the coronal
portion of the fixture and fits into threads of the
internal channel over the hexagonal shape.
oThis is used during the interim period after the
first surgical procedure and before the second
surgery, it has a groove for screwdriver access
and is rounded on top prevent damage to soft
tissue.
o In the centre of the screw there is a depression
within the groove to accommodate the punch
blade; the blade is used for cutting soft tissue
located around the circumference of the cover
screw during second stage surgery.

106. Transmucosal abutment
oAbutments are component of the implant system
that is screwed directly into the implant.
oIt provides the connection between the fixture
and the prosthesis that will be fabricated. They
accept the retaining screw of the prosthesis.
oThe abutment is made of titanium or titanium
alloy.
oAbutments take many forms. Their wall is usually
smooth, polished, straight aided titanium or
titanium alloy.

107. Transmucosal abutment
oThe abutment screw has a silicone ring that
provides a seal to prevent microorganisms from
passing through the abutment to the fixture.
oAbutments can engage either an internal or
external hexagon on the fixture that serves as an
anti rotational device, which is particularly
important for single unit restorations.

108. oAbutments are classified as temporary and
permanent abutments.
oTemporary are healing abutments which are
placed after second stage surgery. They will be
slightly larger than the permanent abutments.
oPermanent abutments are classified according to
length, angulations, material, implant system etc.
oAngled abutments are used in divergently placed
implants. Tapered and wide-base abutments
allow teeth with larger cross sectional diameter to
be restored with more physiologic contours.
110. oHealing abutments are dome shaped screws
placed after second stage surgery and before
insertion of the prosthesis
oThey can be screwed directly into the fixture or
onto the abutment immediately after second
stage surgery.
o Those that screw into the abutment are called
healing caps.

113. oHealing abutments are made of titanium or
titanium alloy.
oIn areas where esthetic is paramount healing
should be sufficiently completed around the
healing cap to stabilize the gingival margin.
114. Impression posts:
oImpression posts facilitate transfer of the intraoral
location of the implant abutment to a similar
position on the laboratory cast.
oThey may be screw into the implant or into the
abutment and are customarily subdivided into
fixture type or abutment type, with the transfer
post in place ,an impression is made intraorally.
oThese can be further subdivided into transfer
types(indirect) and pick up type(direct)after
radiographs are taken to confirm complete
engagement.

115. oWhen impression is removed from the mouth
impression post remains in place on the Implant
or the abutment.
oIt is removed and joined to the laboratory analog
before being transferred to the impression in the
proper orientation
oTo correct implant angulations in the cast flat
sided impression post is used. Completely
symmetrical impression posts are contraindicated
if angle correction is necessary.
116.
117. oImpression posts can also be divided into one
piece or two piece type .
oOne piece type is screwed into the fixture or
the abutment and is used where there is no
need to change the abutment in the
laboratory cast.
o To transfer the orientations of an
antirotational feature from the mouth to the
cast the two piece Pick up (direct) impression
technique should be used.
118. o This requires a two piece impression post with a
removable guide pin that screws directly into the
abutment or onto the fixture.
o It uses a square coping with a long guide pin
and usually an open top tray to prevent rotation
in the impression material and to allow access to
the guide pin for unscrewing after the material
has set so that the copings can be picked up with
in the impression.
119. Laboratory analog:
oLaboratory analogs are made to represent
exactly the top of the implant fixture or the
abutment in the laboratory cast therefore they are
classified as fixture analog and abutment
analogs.
oBoth screw directly into the impression post after
it has been removed from the mouth and
returned to the impression before pouring.
oAbutment analogs are generally attached to an
implant impression post. Implant body impression
posts are normally attached to implant body
analogs.
Implant restorations; A step by step guide, Carl drago
120. Laboratory analog:
oThe advantage of using the implant body analog
is that the abutments can be changed in the
laboratory if the clinician is confident that the
appropriate abutment has been selected using
the abutment impression post and abutment
analog can simplify the procedure.
