Major and minor connectors are important component parts of partial dentures. Major connectors join the components on opposite sides of the dental arch and must provide rigidity while avoiding pressure on soft tissues. Minor connectors join the major connector to other parts like clasps, rests, and the denture base. Both major and minor connectors work together to distribute forces and provide retention, stability, and support for the partial denture.
This presentation specifically deals with the maxillary and mandibular Major connectors used in a cast partial denture. it also mentions the uses, advantages and disadvantages of each,

Many have been interested in Tom Selleck health. not only because of his enduring presence on screen but also because of the challenges. and lifestyle choices he has faced and made over the years. This article delves into the various aspects of Tom Selleck health. exploring his fitness regimen, diet, mental health. and the challenges he has encountered as he ages. We'll look at how he maintains his well-being. the health issues he has faced, and his approach to ageing .
Early Life and Career
Childhood and Athletic Beginnings
Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting
Selleck's transition from an athlete to an actor came with its physical demands. His first significant role in "Magnum P.I." required him to perform various stunts and maintain a fit appearance. This role, which he played from 1980 to 1988. necessitated a rigorous fitness routine to meet the show's demands. setting the stage for his long-term commitment to health and wellness.
Fitness Regimen
Workout Routine
Tom Selleck health and fitness regimen has evolved. adapting to his changing roles and age. During his "Magnum, P.I." days. Selleck's workouts were intense and focused on building and maintaining muscle mass. His routine included weightlifting, cardiovascular exercises. and specific training for the stunts he performed on the show.
Selleck adjusted his fitness routine as he aged to suit his body's needs. Today, his workouts focus on maintaining flexibility, strength, and cardiovascular health. He incorporates low-impact exercises such as swimming, walking, and light weightlifting. This balanced approach helps him stay fit without putting undue strain on his joints and muscles.
Importance of Flexibility and Mobility

New Directions in Targeted Therapeutic Approaches for Older Adults With Mantl...i3 Health
i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection

Lung Cancer: Artificial Intelligence, Synergetics, Complex System Analysis, S...Oleg Kshivets
RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.

3. Major connectors
The part of a partial removable dental prosthesis that joins the
components on one side of the arch to those on the opposite side
(GPT8).
4. Classification
1. Maxillary and mandibular – depending on where it is used.
2. Acrylic and metal – depending on the material used.
3. Rigid and non-rigid – depending on the movement of denture
base.
5. Requirements
1. Should be rigid: This allows stresses that are applied to any part of
partial denture to be distributed over entire supporting area.
6. 2. Must avoid impingement of free
gingival margin
This is a highly vascular area which can get injured by pressure.
Definitive distance must be maintained between:-
(A)the border of the major connector and
(B)the free gingival margin.
7. Maxilla – minimum 6 mm distance
between border of major connector and free gingival
margin.
8. Mandible – minimum 3 mm distance between
border of major connector and free gingival margin.
9. 3. The border of major connector should run
parallel to gingival
margins
10. If margin must be crossed, the crossing
should be at right angles to produce least contact and relief
must be provided
11. 4. Provide vertical support and hence protect the soft
tissue.
5. Provide indirect retention where indicated.
6. Provide for positioning of denture bases where
needed.
12. 7. Should be self-cleansing
and not cause food
entrapment.
The beading is done on
the master cast before
duplication and should
have a width and depth
of 0.5–1.0 mm using
spoon excavator or small
round bur.
13. 8. Maintain patient comfort and should
not interfere with speech and
phonation
21. Types of maxillary major connectors
Palatal bar
Palatal strap
Anteroposterior, or double palatal bar
Horseshoe-shaped, or U-shaped connector
Closed horseshoe, or anteroposterior palatal strap
Complete palate
22. Palatal bar
It is a bar running across the palate which is a narrow half
oval
in cross-section with its thickest point in the centre.
26. Anteroposterior or double
palatal bar
It has basically two bars – one placed anteriorly and the
other
posteriorly, connected by flat longitudinal elements on
each side
of lateral slope of palate
30. Closed horseshoe or
anteroposterior palatal strap
Basically two palatal straps – one anterior and the other
posterior, connected by flat longitudinal elements on each
side of lateral slope of palate.
34. Maxillary major connectors indicated for
kennedy’s classification
Class I: Closed horseshoe, complete palate
Class II: Palatal strap, closed horseshoe
Class III: Palatal strap, palatal bar
Class IV: Horseshoe, closed horseshoe, complete palate
35. Mandibular major connectors:-additional specific
requirements for
mandibular major connectors:
1. They should be rigid
without being bulky
• because of space limitations caused by
floor of mouth,lingual frenum, tongue
and mandibular tori.
36. 2. Relief is always
given.
More relief given when soft
tissues slope towards tongue
(bottom) than when they are
vertical (top).
37. 3. The inferior border should not impinge
on the tissues in the floor of
the mouth.
Height of floor of the mouth is
measured
intraorally
Transferred to cast.
38. Types of mandibular major
connectors
Lingual bar
Sublingual bar
Lingual plate
Double lingual bar
Labial bar
39. Lingual bar
It is a half pear shaped bar with
the superior border located
below the gingival border and
the gingival margin
41. Sublingual bar
It is kidney-shaped,
placed deeper into the
anterior lingual sulcus
when adequate space is
not available for lingual
bar
42. Lingual plate
it is basically a pear-
shaped lingual bar with
superior border
extending onto the
lingual surfaces of teeth
as a thin solid plate of
metal.
43. Lingual plate
In case of gingival recession and spacing in the
anteriors, cut back of the plate can be done to
prevent visibility of metal
44. The anterior lingual plate must always be supported at each
end by rests no further posterior than mesial fossa of first
premolars
Mesial rests on first premolars.
45. Double lingual
bar
The lower bar is similar to
a lingual bar, pear-
shaped in cross-section.
The upper bar should be
half-oval in cross-section,
the middle portion is
removed.
47. Double lingual bar
Rests on mesial surface of
premolars.
Double lingual bar with step
back design
48. Labial bar
Labial bar – major
connector placed labially
Labial bar is indicated when mandibular
anterior teeth are lingually inclined
preventing the use of lingual major
connectors.
51. Minor connectors
The connecting link between the:-
(A)major connector or
base of a partial removable dental prosthesis and
(B)the other units of the prosthesis, such as the clasp assembly,
indirect retainers, occlusal rests, or cingulum rests.
(GPT8)
52. Functions
• Joins major connector with other component parts.
• Transfers and distributes functional stress to the abutment teeth
and residual ridge.
• Transfers effect of retainers, rests and stabilizing components to
the remainder of the denture.
53. Classification
1. Clasp assembly – minor connector
2. Indirect retainer or auxiliary rest minor connector
3. Denture base minor connector
4. Approach arm minor connector
55. Clasp assembly minor connector –
Two types :-
Minor connector adjacent to edentulous
space.
Minor connector in
embrasure.
56. Indirect retainer or
auxiliary rest minor
connector
It connects the indirect
retainer and auxiliary rest to
the major connector
57. Denture base minor connector
• This joins the denture base to the major connector.
• This is of the following types: 1. Latticework construction
2. Mesh construction
3. Bead, wire or nail head
construction
58. 1-Latticework construction
It consists of two struts of metal running longitudinally
along the
edentulous space, with smaller struts running across the
crest of
the ridge connecting the longer struts.
60. 2-Mesh
construction
Consists of a thin sheet of
metal with multiple small
holes extending similar to
latticework construction.
It also requires relief.
61. 3-Bead, wire or
nail head
These are used with a metal
denture base. No relief is
provided. The acrylic resin is
attached only to the superior
surface of metal base and
retention is achieved by
projections in the form of
beads, wires or nail heads
62. Approach arm
minor connector
This serves as an approach
arm for a bar clasp (vertical
projection clasp), supports the
direct retainer and engages
the undercut from the gingival
margin
63. SUMMARY
The component parts of the cast partial denture perform specific
roles
in providing retention, stability and support for the prosthesis. Their
judicious use also helps to preserve the health of the tissues.. Hence,
the
role of each component should be thoroughly understood to help
design
the partial denture for different clinical situations.
