The document introduces the Mini Parallelometer, an instrument that shows the parallelism between dental stumps to ensure they are prepared perfectly parallel for fixed prostheses. It has two parallel pivots on the ends of two legs that can be inserted into the mouth to measure parallelism between teeth regardless of their position. This allows wax patterns to be made that do not distort and for fixed prostheses to fit perfectly on the first attempt. It is made of sterilizable titanium, comes in a small size that can fit in the mouth, and has adjustable legs and pivots to measure parallelism between teeth in both upper and lower arches.

Lingual arch space maintainer
The lingual arch space maintainer is a passive bilateral mandibular appliance used to control tooth movement and arch perimeter after the loss of lower primary molars. It consists of bands on the first molars connected by a stainless steel wire. The wire is positioned to contact the lower incisors and rest on the gingiva of the molared and molar bands. It maintains the arch shape and leeway space until the permanent teeth erupt. Advantages include allowing eruption of permanents without interference and maintaining oral hygiene, while disadvantages include not preventing opposing tooth extrusion and potential for distortion.
Congenitally missing & supernumerary teeth
The document discusses congenitally missing teeth (hypodontia), supernumerary teeth, and their management. It notes that hypodontia affects about 20% of adults and involves missing 1-5 permanent teeth (excluding wisdom teeth). Supernumerary teeth are additional teeth that can occur in any region, with mesiodens being the most common type found in the maxillary midline. Both conditions can cause problems like failure of eruption or displacement. Treatment depends on the specific teeth involved and may include removal, especially if causing issues, or monitoring without removal.
Metal ceramic crown
Metal ceramic crowns are a traditional type of crown often used for bridges and multiple crowns. They consist of a metal interior fused to a porcelain exterior. While considered strong and durable, they are thicker than other crowns and can show the dark metal through the gumline or porcelain over time. They also have a risk of chipping. The process of creating a metal ceramic crown involves shaping the tooth, taking an impression, creating a metal framework, adding porcelain, and cementing the final crown. All ceramic crowns have become more popular due to their superior aesthetics.
Fixed prosthodontics lesson 3
Full coverage restorations include metal crowns, porcelain jacket crowns, and metal-ceramic crowns. Metal crowns provide great strength but poor aesthetics, while porcelain jacket crowns have the best cosmetic results but risk of fracture. Metal-ceramic crowns combine the strength of metal with the aesthetics of porcelain, making them suitable for teeth requiring esthetics or with extensive destruction.
Different gingival finish lines (margins) of crowns and bridges
The document discusses various considerations for margin placement in tooth preparations, including biological, mechanical, and aesthetic factors. It describes advantages and disadvantages of different margin types such as supragingival and subgingival margins. Common margin designs like shoulder, bevel, and chamfer margins are explained. Guidelines are provided for reducing tooth structure during preparation in a systematic manner.
Root resorption
This document discusses root resorption, including its classification into external and internal types. External resorption can be caused by transient stimuli like trauma or progressive stimuli like orthodontic forces. It describes different types of external resorption in detail like surface resorption, inflammatory resorption, and ankylosis related resorption. Internal resorption is usually due to pulpal infection. Invasive cervical resorption is discussed as a type of progressive external resorption caused by sulcular infection. Treatment depends on the type and severity of resorption, and may include nonsurgical approaches like orthodontic extrusion or surgical procedures like flap reflection and restoration.
Facebow part ii
1. The document describes the process of using a digital impression and preliminary jaw relation record to fabricate custom trays (CAD/CAM trays) for making definitive impressions.
2. A digital impression of the edentulous jaws is taken using an intraoral scanner, and a preliminary jaw relation record is made by scanning a jig made of polymerized silicone putty placed between the jaws.
3. CAD software is used to create images of custom trays based on the digital impression and jaw relation record. The custom trays can then be fabricated using 3D printing.
Fixed prosthodontics lesson 4
Partial coverage restorations restore only a portion of the clinical crown and are classified based on retention features like grooves or pins. A 3/4 crown restores the occlusal surface and three axial surfaces, excluding the facial surface. It is indicated for anterior and posterior teeth. Contraindications for partial coverage restorations include when maximum retention is required, with a thin or short clinical crown, in patients with high caries risk, or with active periodontal disease.

removable partial denture survey lines, path of insertion, guide planes
1) Surveying involves marking the height of contour and infrabulge on teeth to determine the path of insertion and areas for retention. Guide planes are then prepared parallel to this path to restrict movement.
2) Analysis determines if the initial survey line provides sufficient retention and whether tilting the cast is needed.
3) The final survey line is marked, selecting retentive undercuts opposing the path of displacement. Guide planes are prepared to further limit movement to a single path.
Palatal contours of denture
This document describes techniques for customizing the palatal contours of maxillary complete dentures to improve speech, specifically production of the sibilant sounds /s/ and /sh/. It discusses evaluating palatal contact during speech using a palatogram, and modifying the palatal contour with tissue conditioner if the denture is under-or over-contoured in the anterior region. Duplicating the patient's palatal rugae using impression materials or wax can further enhance speech and reduce adaptation time. The conclusion recommends keeping the posterior ridge thin and contouring mainly in the anterior palate for best phonetics.
Anchorage in Orthodontics
The document discusses different types of anchorage used in orthodontics. It defines anchorage as the resistance used to overcome the reaction to an applied force. There are different factors that affect a tooth's resistance to force, as well as different types of anchorage including extra-oral anchorage like headgear and intra-oral anchorage that can be intra-maxillary or inter-maxillary. Examples of each type are provided. Temporary orthodontic micro anchorage systems are also discussed as a modern method to reinforce anchorage.
Onlay
The cast metal restoration is versatile and is especially applicable to Class II onlay preparations. The process has many steps, involves many dental materials, and requires meticulous attention to prepration.
Tooth treatment planned to be restored with an intracoronal restoration, but the decay or fracture is so extensive that a direct restoration, such as amalgam or composite, would not be able to sustain or bear forces.
Additionally, when decay or fracture incorporate areas of cusp or remaining tooth structure that undermines perimeter walls of a tooth, an onlay might be indicated.
Shortened dental arch sda
The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive functioning. Exercise causes chemical changes in the brain that may help protect against mental illness and improve symptoms.

Bsp bpe guidelines_2019
The document provides guidelines for using the Basic Periodontal Examination (BPE) screening tool to assess periodontal health. The BPE involves probing 6 sites around each tooth to measure pocket depth and assign a code for each tooth section. Codes indicate the level of care needed, from oral hygiene instruction (Code 0-1) to non-surgical treatment (Code 2-3) to referral for specialized treatment (Code 4). While not diagnostic, the BPE gives a minimum standard for initial assessment and indicates if further detailed examination is required. Practitioners should use clinical judgment and consider unique patient factors when interpreting BPE scores.

It begins with an overview of the Munsell color system and CIElab color system for objectively describing colors. It then covers visual and instrumental shade matching methods and the impact of lighting conditions. Different shade guide systems are described like Vita Classical and 3D-Master. It emphasizes the importance of value, chroma and hue in shade selection. Gingival shade guides and techniques to improve color matching ability are also mentioned. Overall, the document provides a comprehensive review of color science and shade selection principles in prosthodontics.
Banding
This document provides information on banding instruments and procedures in pediatric dentistry. It discusses the history of bands, various band materials and sizes, advantages and disadvantages of bands, ideal band material requirements, instruments used for banding, and banding techniques. The key points are:
- Bands are thin metal rings placed on teeth, typically molars, to secure orthodontic appliances. Accurate band placement is important for fitting appliances.
- Stainless steel is commonly used due to properties like resistance to tarnish and springiness. Band sizes vary based on tooth type.
- Banding provides strong attachment but risks caries if cement seals fail. Autoclaving is the most reliable steril

Surveyor and technique of Surveying in Removable partial denture
The document discusses surveying in removable partial dentures. It provides information on the history and development of dental surveyors. Key aspects covered include:
- The purpose of surveying is to determine the path of insertion, guiding planes, and contours for the design of removable partial dentures.
- Early instruments included paralleling devices and the first dental surveyors developed in the 1910s-1920s.
- Modern surveyors consist of a level platform, vertical arm, and interchangeable surveying tools to assess contours, undercuts, and plan the path of insertion.
- Surveying involves an initial assessment, analysis of retention and interference, and final survey to determine the survey lines and design of clasps
theories of tooth movement
The document summarizes theories of orthodontic tooth movement including the pressure-tension theory and bone-bending theory. It discusses how application of orthodontic forces leads to remodeling changes in the periodontal ligament and alveolar bone through pressure and tension sites. Key signaling molecules that mediate the biological response to orthodontic forces are also summarized, including prostaglandins, cytokines, and growth factors that regulate bone resorption and formation during tooth movement.
Resin bonded fixed partial denture
This document discusses resin bonded fixed partial dentures (RBFPDs). It defines RBFPDs as prostheses that are luted to tooth structure using composite resin. Various types are described, including cantilever, fixed-fixed, and hybrid bridges. Advantages include reduced cost and minimal tooth preparation. Indications are for replacing single missing teeth with caries-free abutments. A case example describes using an RBFPD to replace a missing mandibular incisor and splint mobile abutment teeth.
crown lec1- principles of tooth preparation(v.good)
The document discusses various aspects of tooth preparation for dental restorations. It covers principles such as retention, resistance and prevention of undercuts. It describes preparation designs for different types of restorations like crowns, bridges, veneers and describes finish lines. Biologic considerations like preventing damage to adjacent teeth and pulp are covered. Mechanical principles like adequate tooth reduction, taper, and smoothing of line angles are explained.
Micro abrasion
This document compares and contrasts microabrasion and macroabrasion techniques for treating tooth discoloration. Microabrasion involves using a paste of hydrochloric acid and pumice or silicon carbide to dissolve and abrade the enamel surface. It is a conservative treatment that removes only superficial stains. Macroabrasion uses diamond or carbide burs to remove defects at a faster rate but with less control than microabrasion. Both techniques can improve the appearance of teeth affected by conditions like fluorosis but microabrasion allows for better control and more conservative removal of tooth structure.

Method for determining central occlusion and central jaw.pptx
Method for determining central occlusion and central jaw ratio. Fixation of dentition in central occlusion using occlusion registers. Devices that reproduce the movements of the lower jaw-occluders, articulators. The principle of working with them.
Mustafa al-ali, 48
Anatomical method
is based on determining the correct configuration of the lower third of the face. Giziand Keller point to the following anatomical features that must be followed:
1 -the lips should move and without tension touch each other all the way and should not be sunken, the circular muscle of the mouth should function normally;
2 -The corners of the mouth should be raised, nasolabialfolds should be clearly expressed. This method is very subjective.
Anatomical method
based on the study of the proportionality of parts of the human body. Harringeninvented a compass that solves the problem of the golden section, freeing the physician from algebraic calculations and geometric constructions. This method is not accurate enough.
State of relative physiological rest
Anatomical and physiological method-is based on the fact that the relative physiological (functional) rest of the mandible is 2-4 mm higher than the height of the central occlusion. First, determine the height of the relative physiological rest (determined by muscle tone, myotaticreflex and passive forces that hold the lower jaw in space, as well as the elasticity and elasticity of the epithelial tissues). This height is measured with a spatula or ruler. Then fit the record blocks, so that the height when closing the blocks was 2-4 mm lower.
–is one of the articulation positions of the lower jaw with minimal activity of the masticatory muscles and complete relaxation of the facial muscles. The tone of the muscles raising and lowering the lower jaw is equivalent

Devices that reproduce the movements of the lower jaw-occluders
Dental articulators are mechanical instruments that allow you to recreate the relationship of the temporomandibular joint (TMJ) with the jaws, by mounting the upper and lower impression models on the instrument.
The articulator simulates the patient's mandibular movements; providing the static and dynamic relationships in order to observe malocclusions or dysfunctionalities extraorally. Thanks to this, the dentist can study way the treatment guidelines without causing fatigue or discomfort for the patient.
types of dental articulators exist?
Non-adjustable articulators (Class I)
Also known as hinged occluders or hinges, they cannot really be considered articulators, as they are simple support instruments. They only reproduce the static relationship with the mounted model, their advantage is that they are small instruments and allow an easy and quick organisation of the models.
An example of this type of articulator is the quick-fixing ar

COMBINATION ANCHORAGE TECHNIQUE / dental crown & bridge courses
The document discusses the Combination Anchorage Technique (CAT) in orthodontics. CAT combines elements of the Begg technique using light wires in the gingival bracket slot with the straight wire technique using more rigid wires in the horizontal slot. The summary is:
1. CAT aims to use light wires in the gingival slot early in treatment for tooth movement, then transition to more rigid straight wires later for precise finishing.
2. Bracket and wire designs have improved to reduce friction and increase control of tooth movement. Tandem and dual flex wires provide flexibility and rigidity where needed.
3. Treatment involves phases using different wire positions and mechanics to efficiently align, level, retract,

Breast cancer: Post menopausal endocrine therapy
Breast cancer in postmenopausal women with hormone receptor-positive (HR+) status is a common and complex condition that necessitates a multifaceted approach to management. HR+ breast cancer means that the cancer cells grow in response to hormones such as estrogen and progesterone. This subtype is prevalent among postmenopausal women and typically exhibits a more indolent course compared to other forms of breast cancer, which allows for a variety of treatment options.
Diagnosis and Staging
The diagnosis of HR+ breast cancer begins with clinical evaluation, imaging, and biopsy. Imaging modalities such as mammography, ultrasound, and MRI help in assessing the extent of the disease. Histopathological examination and immunohistochemical staining of the biopsy sample confirm the diagnosis and hormone receptor status by identifying the presence of estrogen receptors (ER) and progesterone receptors (PR) on the tumor cells.
Staging involves determining the size of the tumor (T), the involvement of regional lymph nodes (N), and the presence of distant metastasis (M). The American Joint Committee on Cancer (AJCC) staging system is commonly used. Accurate staging is critical as it guides treatment decisions.
Treatment Options
Endocrine Therapy
Endocrine therapy is the cornerstone of treatment for HR+ breast cancer in postmenopausal women. The primary goal is to reduce the levels of estrogen or block its effects on cancer cells. Commonly used agents include:
Selective Estrogen Receptor Modulators (SERMs): Tamoxifen is a SERM that binds to estrogen receptors, blocking estrogen from stimulating breast cancer cells. It is effective but may have side effects such as increased risk of endometrial cancer and thromboembolic events.
Aromatase Inhibitors (AIs): These drugs, including anastrozole, letrozole, and exemestane, lower estrogen levels by inhibiting the aromatase enzyme, which converts androgens to estrogen in peripheral tissues. AIs are generally preferred in postmenopausal women due to their efficacy and safety profile compared to tamoxifen.
Selective Estrogen Receptor Downregulators (SERDs): Fulvestrant is a SERD that degrades estrogen receptors and is used in cases where resistance to other endocrine therapies develops.
Combination Therapies
Combining endocrine therapy with other treatments enhances efficacy. Examples include:
Endocrine Therapy with CDK4/6 Inhibitors: Palbociclib, ribociclib, and abemaciclib are CDK4/6 inhibitors that, when combined with endocrine therapy, significantly improve progression-free survival in advanced HR+ breast cancer.
Endocrine Therapy with mTOR Inhibitors: Everolimus, an mTOR inhibitor, can be added to endocrine therapy for patients who have developed resistance to aromatase inhibitors.
Chemotherapy
Chemotherapy is generally reserved for patients with high-risk features, such as large tumor size, high-grade histology, or extensive lymph node involvement. Regimens often include anthracyclines and taxanes.
Cell Therapy Expansion and Challenges in Autoimmune Disease
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.

We’re talking about Vedic Meditation, a form of meditation that has been around for at least 5,000 years. Back then, the people who lived in the Indus Valley, now known as India and Pakistan, practised meditation as a fundamental part of daily life. This knowledge that has given us yoga and Ayurveda, was known as Veda, hence the name Vedic. And though there are some written records, the practice has been passed down verbally from generation to generation.How to Control Your Asthma Tips by gokuldas hospital.

Unfortunately it is uncomfortable for the patient, who has to keep still on the head-rest through a proper system of locking. We think it is an high price for him. Not to rinse his mouth and rest during a long preparation time, it is inconceivable!
- 19. Some years ago the dental market proposed a mirror, on which different parallel lines were carved. The mirror should be inserted into the oral cavity and, externally, the operator winking or closing one eye, should find out the disparallelism between the stumps. But the use of the mirror was limited to the elements on one side in the oral cavity. And mistake of parallax was one of the cause for the lack of correct date.
